Description: Math triangles ADDITION & SUBTRACTION is a fun series of cards to help with practicing adding and subtracting simple numbers. Using the triangle on the left, there are 4 equations that can be formed which are listed on the right - 2 addition and 2 subtraction equations. Simply fill in the missing numbers to solve all 4 equations using the numbers in the triangle. There are 30 question cards in all. The first 10 have 4 numbers missing which need to be identified and entered. The second 10 have 6 numbers missing and the third 10 have 8 numbers missing. An instruction card at the front shows graphically what you need to do. You can complete the equations by solving the sums or by entering the numbers into the correct position based on the position of the numbers in the triangle. By exercising this way, the student starts to spot and recognise the patterns and thus learns how to complete the equations.
