Today is a practical lesson so grab what you can, pencils, pasta, coins - what ever you have to hand to represent numbers. If you have two types of pasta, one could be tens and the other ones.
Today we're consolidating what we looked at last term - to find one more and one less than a given number. We're continuing to work with numbers up to 50.
Use the number line, pick a number and then find the number that is one less and the number that is one more than that number. This is where the objects you've collected can help. Once your child has given an answer, follow it up with 'How do you know?' or 'Prove it.' They could use the objects they've collected or, if they feel confident, they could draw their response.
Ask them to write it in different ways:
_____ is one more than ____
One less than _____ is _____
