This is a game for the whole class. It can be played a few times as a lesson starter. The teacher will need a 0 to 9 spinner or dice.
All the learners should draw in their notebooks a hundreds, tens and units grid as shown. The teacher spins the spinner and the learners choose one of the 4 boxes in this addition sum and write the digit in their chosen box. This is repeated for three more spins. The learners then add the two numbers and the winner is the learner who gets the total closest to 100.
The whole class should check the additions that are claimed to be closest to 100.
Click here for a template to make your spinner. Mark in the lines in the template and cut it out. You will need a paper clip and a pin. Open out the paper clip and pin the paper clip and the template down on a flat surface so that the paper clip spins easily. You could use a die instead if you have one.
