Counting by 3s, 4s, and 5s

Skip count along the mushrooms to complete these number sentences which give young scholars an introductory look at addition and subtraction. Starting from five double-digit numbers, they subtract or add by threes, fours, and fives to fill in four mushrooms in the sequence. Each problem has one number in the sequence given to help learners evaluate their calculations. Encourage them to follow the example by drawing in the arrow and operation between each mushroom.
