- Help your child practice partitioning household items (pieces of paper, portions of food, a pack of crayons, etc.) into equal parts.
- Get a package of index cards and work with your child to see how many different “halves” you can cut out of the index cards. Challenge each other to get creative and defend why the images you create are (or are not) halves! Repeat this for other fractional units, such as thirds, fourths, sixths, and eighths.

- Give your child some measuring cups, several bowls that are exactly the same size, and a pitcher of water. Ask questions like, “What contains more water, 2 one-third cups or 2 one- fourth cups?” Have your child fill the measuring cups with water and then pour the water int the bowls to compare the amounts of water side by side. Talk about why one bowl has more water even though your child added 2 units of water to both bowls.

- Ask your child to teach you how to add and subtract fractions. Teaching you will help him to explain his thinking as he talks through the process. Ask him to explain how the models (the number bond, number line, and tape diagram) can help him solve.
- Together, find one of your child’s favorite recipes. Look at the amount needed for each ingredient. Pose the following questions: What happens if we want to make two batches of the recipe instead of one? How much of each ingredient will we need?
