Odd Even number investigation (to 100)

What’s included?
This download includes x2 landscape orientation pdfs to investigate odd and even numbers up to 100.

Who’s it for?
This resource has been designed for pupils in years one and two as well as older students needing additional learning support.

Resource layout
Page 1 features a hundred number square and simple instructions for learners to circle or colour each number (red for odd numbers and green for even numbers) depending on whether the numbers are odd or even. Learners will need to be familiar with what ‘odd’ and ‘even’ means and if they don’t already know which of these numbers are odd or even they will need to know how to work this out.

After completing the 100 number square there is a question (in the blue cloud shape on the left) asking learners ‘What do you notice?’ - this is to encourage learners to identify that once the numbers have been coloured there is a red/green repeating colour pattern. There is a space on the left for learners to record their own answer to this in the blue box provided or learners could articulate their observations to an adult who could write this for them as needed.

There is a clear space for learners to write their name at the base of page 1 (on the left) as well as recording the number date at the top (on the right).

Page 2 features two large boxes - red for odd numbers (on the left) and green for even numbers (on the right). At the base of sheet there are x15 (random) numbers (up to 100) for learners to cut out (following the dotted lines) and sort into the red/green boxes above. Learners could use their completed page 1 as a reference to help with completing page 2.

There is a clear space at the top of page 2 (on the left) for learners to write their name as well as recording the number date (on the right).

What’s needed?
Page 1. Learners will need:

• a red and green pencil/crayon/felt tipped pen
• a pencil

If using pen I would encourage learners to ‘circle’ each number (rather than ‘colouring them in’) to avoid the paper becoming saturated with pen - particularly if learners will then use page 1 as a reference to complete page 2.

Page 2. Learners will need:

• a pencil
• scissors
• a glue stick
