We were working on counting forwards and back from given numbers within 20 0r 30. First we recited the numbers forwards and backwards (backwards is very tricky... we need to keep practising this!) Then we ordered all the numbers independently. After that we answered questions about the numbers, such as 'Which number is one more than 18?' 'Which number is one less than 30?'
Can you spot any mistakes?
For example, Can you count from 51 back to 24? Can you count from 18 to 25? How many steps is that? Can you count from 47 back to 17? Which number comes before 70? Which number is 40 one more than? Which number is one less than 30?
