Number representations to 20!

Today we are looking at the different ways we can represent numbers to 20.  This week we have ordered, counted and made up numbers to 20 and to end our week of teen numbers we are looking at the different ways we can make up to twenty.

In class we use bead strings, counting objects, our fingers/hands, number cards, dice and Numicon as our most common and familiar methods to represent numbers. All of these things give children a visual understanding of what each number stands for. This may seem initially basic, but as concepts get trickier it becomes very important that children have strong foundations not just in mental recall, but of what a number is made up of and what that looks like in different forms. It helps children with their understanding as well as giving additional methods of working.

Below are a range of activities that you can use. They all centre around matching the representation to the number. Prepare to get handy with scissors and sticky with glue!

The first document 'Visual Number Line' is not an activity as such but useful number cards that you can now use with your child and/or display them at home. You can also use these as an answer card or reference when completing the other activities. You don't have to print this number line out A4 size, simply change the settings when you go to print to fit two or four on a page.

Need a stepping stone?

Complete the activities but stop at ten, or at the teen numbers that begin to cause a real challenge. It is important that your child is secure with their numbers to ten before moving on to numbers up to 20. Saying that, it is important that your child is becoming familiar with numbers up to 20 at this point in the year so having the visual line up in the correct order to 20 in your house will be very valuable.

Need a further challenge?

Can your child create numbers up to 100 based on the form of representations shown today? Could they make the numbers using Numicon, coins, towers of building blocks (Duplo or Lego will work!). This will help to build your child's understanding of tens numbers.
