About the Mathematics in This Unit

Benchmark/Goal Examples
Use addition and subtraction to solve word problems involving measurement. Carmen flies from Los Angeles to Mexico City, which is 4,771 kilometers. From Mexico City she flies to Rio de Janeiro, which is 7,678 kilometers. How far does she fly altogether?

In our math class, students spend time discussing problems in depth and are asked to share their reasoning and solutions. It is important that children solve math problems accurately and efficiently in ways that make sense to them. At home, encourage your child to explain the math thinking that supports those solutions.

Please look for more information and activities about Large Numbers and Landmarks that will be sent home in the coming weeks.
