# Comparing Numbers up to 20

As the number of objects gets larger, it can become harder for children to recognise which of two or more groups have more or less. In this section we provide practice with hands-on ideas and worksheets, and also encourage children to group objects together in order to be able to "see" the numbers better.

## Ideas for Learning

• Guessing, grouping and counting. Give your child two piles or counters or buttons with somewhere between 11 and 20 in each pile. Ask which pile has the most. Discuss and experiment with tactics to make it easier to tell which group has the most. Here are some ideas, but your child may come up with more.
• Stacking into towers - if the objects are all the same, like counters or small bricks.
• Arranging into careful rows - one above each other.
• Grouping into 5s and then 10s - and then counting the extras.
• Grouping into "10 plus" - counting 10 objects from each group and pushing them to one side, then count the "plus" - ie the remaining objects.
• Grouping with frames - using our Numbers to 20 Frames or Numbers to 20 Towers, or even our Ten Frames Posters 11 to 20, to line up the objects.
• Which of these tactics make it easier to tell which group has more?
• Does it make ir harder or easier if the difference between the group is big or small?
• Which of these methods helps your child to count the number of objects in each group the quickest and most accurately?
• Revise the vocabulary of comparing - greater and smaller, more and more than and fewer and less than and the same.
• Mix and match cards. Use a set of our mix and match cards below, starting with cards that are arranged in arrays (dot set 1 and mouse cards) and moving on to the randomly arranged cards later. Pick two cards and decide which has the most and the least. You can also mix the sets together to make it harder.
• Mix and match cards with More or Less Mats. Print out our More or Less Mats (also available as More and Fewer) and give the children 2 mix and match counting cards at a time. They must count, find the correct number card and arrange them on the mats correctly. Move on to another pair. When children get confident you could give them 6 cards at a time and ask them to arrange them on the mats so that each row is correct. We've shown our puppy cards but you can choose any of our mix and match cards, or muddle them up to make it more challenging.

• Using our Counting Posters. Our colourful counting posters (below) are designed with a space for your child to fix one of our Mix and Match cards. Hold up 2 posters and see if your child can guess which has more and which fewer before counting to see if they were right.
• Worksheets. When you child has mastered the concept, have a go at some of the worksheets below. You can download them as 2 sets of 4, or individually. Set 2 includes a Halloween and Christmas worksheet.
