A Perfect Fit

Activities

• Have a whole-class session ‘throwing’ 2-digit numbers that add to 100. You start by calling out a 2-digit number. The children have to ‘throw’ back, in unison, the number that makes it up to 100. Start with multiples of ten, then five before trying other numbers.
• Put up some 2-digit plus 2-digit additions on the board. Ask the children to work in pairs to make up some ‘story’ problems using the numbers.
