  • Have your child recognize arrays in real-world situations (e.g., a carton of eggs, a pack of water bottles, a cupcake baking pan, a checkerboard). Help your child distinguish between the terms row and column.

  • Place various objects into arrays in your daily life, such as crackers on a plate, crayons, or toys that your child may have. Say to your child, “How many rows are there? How many objects are in each row? Let’s skip-count the rows to find the total.”

Doggy Division

Multiply a two-digit number by a one-digit number using partial products and the standard algorithm

  • Create a game to practice multiplication facts with your child. Each of you will need ten index cards or small pieces of paper. Number the cards so each of you has one card for each digit (0–9). Place the cards facedown in a pile. One player picks up two cards. The other player has to multiply the numbers shown on the two cards. Switch roles.

  • With your child, read a magazine article or a page from a book. Together, use the context of what you’ve read to create a word problem.
