This week and last week we have been adding and subtracting 2 and 1 digit numbers. We have done so well and can use a number line or a 100 square to help us. Today we played a subtraction and addition lego board game with a partner. We started with 5 blocks of lego each and worked our way around the board, either adding or taking away pieces, depending on the instruction. The person to finish with the most pieces won!
