Description

This pack contains 32 Difference Tower Cards.  Each card has two towers, with each tower carefully created in groups of 5 cubes in alternating colours.  This colour pattern makes it straight forward to work out how many cubes there are in each tower without counting them using one-to-one correspondence.

Instructions: Print out all 8 sheets, laminate and cut into quarters to create 32 Difference Tower Cards.

Ideas for Use:
1) Trading Cards – each child is given a card and encouraged to move around the room, reasoning with another child about their cards before trading them.  Children them move to another partner.  Encourage the children to use the language of difference.  A child might state that, ‘The difference between 12 and 7 is 5.’
2) Equation Generation – Children have a set of cards.  They turn over a card and then record the equation in their books.  The highlighted box would engender: 12 – 7 = 5 (Remember subtraction is about finding the difference between two numbers or quantities.)
3) Cube Tower Creation – children turn over a card and have the challenge of creating another tower with the same difference.  This could then recorded, e.g. 12 – 7 = 10 – 5.
