I See Problem-Solving – LKS2: Support and Challenge

I’m delighted to have released I See Problem-Solving – LKS2. It’s a resource that I’ve lived and breathed in the classroom over the last 10 months! The aim is to help all children to access rich problem-solving tasks, whilst ensuring that all children are challenged and engaged. It is the practical outworking of the research on solving problems from this EEF report (see point 3). 

I See Problem-Solving – LKS2 is comprised of 54 tasks. Each task gives various challenges: the Build prompt introduces the key themes and concepts, before the main Task is presented. Then, there is a Support prompt to help children access the task. The Explain and Extend challenges give rich opportunities for extended exploration.  Here’s an example task, starting from the Build prompt:

This introduces some of the key language that the children will need to understand before they access the main task. Here is the Task:

Children might choose 1, 2 and 3; they could work with 21, 22 and 23. Either way, we can all explore this idea and visual representations can be used to help. If children are need help, they can look at the Support prompt:

The Worked Example shows the solution to the main task step-by-step. The Worked Example can be viewed as a PowerPoint or as a PDF:

To deepen the challenge, the Explain and Extend prompts provide related challenges:

Not all the tasks follow this exact format. Sometimes there are Practise questions:

And there are always questions that extend the challenge:

Information about the resource, plus a link to the Etsy page to buy the resource, is found on the I See Problem-Solving – LKS2 page. There are 5 free example tasks to use too. It costs £24.98 and is available as a digital download of the PDF file. I hope you find this resource super-helpful for engaging children in meaningful problem-solving. It’s certainly given me many great classroom moments already!

Place Value: Seeing the Relative Size of Numbers

In place value, children learn about the value of each digit in a number (e.g. that the 5 in 153 represents 5 tens) – the Deepening Understanding in Column Value blog gives some ideas for extending thinking in these lessons. However, to give children a more complete understanding it’s important that they can also reason about the relative size of numbers. In this blog I will explore how I’ve used a blank number line to develop this form of understanding and look at the wealth of opportunities for reasoning that it can provide.

Consider this task. Children are given a long number line with 0 and 100 at either end and are asked to position 31, 39 and 84 accurately on the number line. Children are challenged to think about whether the lengths between the numbers are appropriately sized.

I have found that children are generally able to order numbers, but that the common mistake is to make the spaces between numbers too similar. In this example, I may ask children to compare the distance between 31 & 39 with the distance between 0 & 31 (which is almost four times longer) and the distance between 84 & 100 (which is exactly twice as long).

In a similar task, children have positioned 4, 7 and 9 on a 0-10 number line. It’s common for children to position 4 by counting four small ‘steps’ on from zero (placing 4 far too close to zero) rather than thinking about the position of 4 relative to the half-way point of the line. Similarly, 7 and 9 are often positioned by counting back from 10, leaving an overly large gap between 4 and 7. With careful modelling, and by looking at the number lines in the classroom, children learn to reason spatially with greater precision.

I’ve included two such tasks in I See Problem-Solving – LKS2 (click on the link for sample tasks), which is due to be released on 29th September. Here’s one of the pages from the Worked Example:

And here is the extension prompt for the task. There’s so much additive and multiplicative reasoning that go into estimating the value of the missing numbers:

I would love to hear about any practical examples of how you are outworked these ideas in the classroom. The blog Deepening Understanding of Column Value gives some more ideas for how to deepen the challenge in place value. Have a great term!

Deepening Understanding of Column Value

When learning about place value, an emphasis is placed on the column value of each digit. For example, the value of the digit 7 in 273 is 70. In this blog I will look at two ways to extend this understanding of place value. In the blog Seeing the Relative Size of Numbers I explain another important building block in children’s knowledge of number.

A child is asked to show 32 using dienes blocks. They get three tens and two ones. I ask the child to show me 32 in another way. Do they recognise that they can use 32 ones? Given two tens, I ask ‘How many more ones make 32? We see that 32 is also two tens and twelve ones.

This basic idea is the foundation for many place value investigations. For example, the I See Reasoning question ‘How many ways can 0.32 be made using 0.1 and 0.01 coins?’ One of the I See Problem-Solving – LKS2 tasks also explores this idea: it’s one of the free sample tasks which can be downloaded from this page. The ‘build’ task introduces the idea of making 230 in different ways:

The main task presents this challenge:

There are ‘support’ and ‘explain’ tasks. Here’s the ‘extend’ prompt:

Of course, 423 can be made with four 100s, two 10s and three 1s. It can be made with 423 ones. There are so many combinations beyond that to be explored.

Another of my favourite types of investigations are ‘sum of the digits’ tasks – this blog gives an example from I See Problem-Solving – UKS2. Here’s how you can introduce a sum of the digits question. To start off with, present this question from I See Reasoning – UKS2, but with part of the instruction covered up:

The correct answer is 102 and 98. Then the sum of the digits element of the question can be uncovered:

Children have to find ways to increase the digit sum for the 3-digit number without increasing its size too much (e.g. increasing the ones value), and how the sum of the digits for the 2-digit number can be reduced without making the number significantly smaller. Should the 9 be used in the ones column for the 3-digit number or the tens column for the 2-digit number? It’s one of my favourite tasks!

The blog Deepening Understanding of Column Value gives more ideas for how to develop children’s understanding of large quantities. I would love to hear from you if you use any of these ideas or questions in your classroom. I hope you enjoy getting to know your new class!

Guest Post: Supporting maths at home can help tackle maths anxiety

This is a guest post by Jill Cornish, Editorial Director, Primary Maths, Oxford University Press

Maths anxiety is a huge issue across the UK from early childhood into adulthood. National Numeracy have found that across the UK four in five adults have a low level of numeracy and individuals earn less when they are less numerate .

Everyone involved in influencing education has a role to play in tackling maths anxiety, from teachers and families at home to media and government. Maths anxiety can be contagious. Parents and carers who aren’t confident with maths themselves often inadvertently pass on these feelings to their own children, creating a cycle of negativity around maths.

As part of Oxford University Press’s Positive About Numbers campaign, we recently ran a series of teacher-led hackathons with primary schools across the country. These were designed to give teachers a safe space to share their experiences of maths anxiety in the classroom and start to pool ideas about practical ways to reduce it.

Amongst other issues, bringing together this wealth of professional insight highlighted the importance of taking a holistic approach to tackling maths anxiety across the classroom and at home. While many teachers are aware of the challenges and potential impact of maths anxiety, parents and carers may not have the background or resources to help their children overcome this barrier to learning. This is why collaboration between school and home is so crucial.

It’s important not to add more pressure or overwhelm families who may already feel nervous about maths. The hackathons identified many light-touch ways teachers can support families to be confident about helping children develop a positive maths attitude. It could be as simple as signposting trusted resources for learning at home, or encouraging families to introduce gameified elements of maths, for example through puzzles and quizzes. Small changes at home can make a big difference to young learners’ attitude to maths over time.

Teachers who took part in the hackathons also highlighted the importance for children of making meaningful links between maths and everyday life. Cooking with the family at home or keeping score in games can engage young children with maths in a way that really brings it to life.

One of the main challenges for teachers is that maths anxiety is not always easy to spot. It can be displayed in many different ways depending on the child and these presentations are not always obviously linked with maths anxiety. Some children may openly copy or make up answers, some may be unusually quiet, other may act up and be disruptive in the classroom. This challenge is even greater for parents and carers who don’t see their children in a structured learning setting. This makes open communication between school and home even more important.

To support teachers and families we’ve pulled together helpful tips and advice from the Positive About Numbers hackathons and combined them into a toolkit with easy-to-use learning resources for the classroom and home. The toolkit has lots of practical ways for teachers to start to address maths anxiety in their lessons, alongside ideas to engage parents and carers with their children’s maths development at home too.

Working together, we really can inspire children to be positive about numbers from an early age.

Please see more details on #Positiveaboutnumbers here, and download a free toolkit with some great ideas for teachers that brings together tips and learnings from the teachers who contributed to the Positive About Numbers hackathon events.

‘Early Number Sense: Helping at Home’ video series – your thoughts!

I passionately believe in the Early Number Sense Helping at Homeimportance of children’s early maths experiences. My training and resources are designed to help children become fluent with small quantities, develop counting skills and learn to reason mathematically.

In my work supporting schools, teachers often comment on how great it would be to show parents how they can best support their children in maths at home. Parents might, for example, teach their children to count to 100. However, skills which are more predictive of children’s long-term success, like the ability to subitize small quantities, have not been developed. This is where I can help.

Over the 2019 summer holiday, I plan to make four YouTube videos to show parents how they can best support their children’s early mathematical development. This series of videos will be called Early Number Sense: Helping at Home. Each video will be approximately 2 minutes long, explaining key principles and giving lots of practical ideas for exploring maths at home. The video titles are Developing Counting Skills, Recognising Quantities, Maths Around Us and Playing With Maths. They will be available on my soon-to-be-established YouTube channel and compiled on a new page at www.iseemaths.com.

I want these free videos to be as good as possible and reach as many parents as possible; for that I am seeking your help. Firstly, please pass this information on to your headteacher or EYFS leader. Also, I would be so grateful if you would FILL IN THIS SHORT QUESTIONNAIRE to tell me what I can do to make the videos as effective and user-friendly as possible. All ideas are welcome!

I have recently been running an innovation project with NCETM Maths Hub NW3 – the work group participants suggested that they would use the videos in their ‘meet the parents’ events in September and share the videos on their school websites. I will explain how this can be done once the videos have been created.

I can’t wait to get your thoughts and ideas about this project. Again, please feed your thoughts through to me via this short questionnaire.

Many thanks and have a great summer – Gareth

I See Problem-Solving for LKS2 and KS1 – update 1!

After completing I See Problem-Solving – UKS2, I spent some time before Christmas extending my free resources for Early Number Sense and creating some free resources for visualising multiplication. Now it’s time for the next big project – writing I See Problem-Solving – LKS2 and I See Problem-Solving – KS1!

I’ve decided to write both resources simultaneously. Trialling the tasks takes so long, I thought was better to get going on both resources now. This will mean I can keep sending out sample resources to be trialled, keep making improvements to both and hopefully, overall, complete the I See Problem-Solving trilogy sooner! So far I have come up with loads of draft ideas for both resources in each curriculum area:

Soon I will start creating the tasks themselves. I’m going to start with tasks in addition and subtraction, multiplication and fractions. The idea is that the pre-task steps will help children to learn the sub-skills for answering the main task, making the activities accessible for all. Then there will be reasoning tasks and extensions for deepening learning. Expect lots of visual, thought-provoking mathematics!

Example tasks will be sent for trialling to people on my trial resources list for KS1 and LKS2: expect the first email mid-February. It helps so much when people tell me what they like about the sample tasks and what can be improved. I’m still very busy with my teaching and training commitments, so if I’m a bit delayed that’s why!

Once all the trialling is done, hopefully the finished product will help teachers to do something that I always found hard: systematically teach problem-solving skills to children. I’m mega-excited about what can be achieved.

I See Reasoning – KS1 and I See Reasoning – LKS2 are designed to help teachers build reasoning into daily maths lessons.

Learning to Problem-Solve: number sequences and negative numbers

This is the first in a series of blog posts about how to systematically teach problem-solving skills using I See Problem-Solving, outworking the EEF research (recommendation 3) about using rich problems to learn mathematics.

Here’s the task that the class were given part-way through the lesson:

Before we get to this point, I want to break down the sub-steps involved in answering this question. First, a little pre-teach group are given this open task to bring back some prior learning:

Then we show the first part of the question that we are building up towards answering and these three example sequences. The children calculate (or spot) the first and then the second negative number in each sequence:

Now the children have a go at this short task. They identify that -4 is the second negative number in the first two sequences. I explain that, when writing the first two sequences, I actually started from -4 and added in equal steps, rather than starting from the positive number and subtracting (which would be more akin to trial and error):

Now the children are equipped to deal with the task. We work to find all the possible answers, noting that the sequence must decrease by more than 3 but less than 7. There ‘support’ prompt for children who need help, and some children also attempt the ‘explain’ or ‘extend’ tasks:

The free I See Problem-Solving Worked Example is used to show the three possible solutions. The following day, we pick up on a few misconceptions and look for ways to become more efficient, including looking at the example above and considering how we could add a multiple of 4 and 5 rather than the repeated adding.

I’m trying to make problem-solving accessible for all children, whilst ensuring that every child is challenged. I hope you find I See Problem-Solving super-helpful. The LKS2 and KS1 versions are in production!
