Part 1: Follow along with your instructor. Add the blocks together. Before you write your final answers, remember to combine (regroup) the tens into groups of 10 (in order to make a hundred) so that the blocks are easier to count.

Part 2: Follow along with your instructor to see how problem A1 above is described by problem A2 below. Then, solve the remaining problems. Remember, only one digit (0, 1, 2, 3, 4, 5, 6, 7, 8, of 9) can be written in each place value column.
