This is an activity that uses the countdown number activity format. The children must choose between large and small number and try to get as close to the total as possible by adding, taking away, multiplying and dividing.
This is a super activity to encourage children to see patterns in functions and numbers.
Division and Remainders
The game will think of a number between 1 and 100. You must use the clues to guess what that number is. The less clues you have, the more points you get.
Factors and Multiples
Click on a number to move it between the two grids. The aim of the game is to make the longest possible chain where each number is a factor or a multiple of its predecessor.
