Estimating Sums and Differences As you encounter fractions in everyday life (such as cooking or measurement), ask your child questions about sums or differences. For example, if you're cooking, ask your child if you have enough (sugar, flour, milk) for the recipe; about how much more is needed; what the total number of (cups) of dry ingredients would be.

How Did You Solve That? As in other Investigations units, students develop several strategies that make sense to them for solving fraction problems. When you see your child using a strategy that is not familiar to you, ask for an explanation. The conversation will be educational for both you and your child.
