Rat Catcher Subtraction

SKU: C009

ACMNA030  MA1-5NA This is a game using subtraction on the decade from 10 - 100.  Played in pairs, each player requires a board and each pair uses the double spinner included in the game.  The object is to catch (cover) all the rats on the board by subtracting the total of the numbers spun and covering the result of that calculation on their board. This is an excellent way of helping to take the fear out of calculations to 100 by dealing with only tens and if students have had plenty of opportunities to build subtraction facts to ten, they should be able to use that knowledge to build subtraction facts from 100 on the decade.  1 set = 2 boards & 1 double spinner
