The Assessment Book is designed to help teachers track student progress and identify areas where extra support may be needed. The Answer Key provides detailed answers for all the questions in the book.

Unit 1: Number and Operations in Base Ten

In this unit, students will extend their understanding of place value to include numbers up to one million. They will use their knowledge of place value to fluently add and subtract within 1000, and they will solve problems involving elapsed time and money. Students will also begin working with decimal fractions, representing them on a number line and estimating quantities using benchmark fractions. By the end of the unit, students should be able to answer questions such as: How can you use place value to represent numbers up to one million? How can you use your understanding of place value to fluently add and subtract within 1000? What strategies can you use to estimate sums and differences involving decimal fractions?

Unit 2: Measurement

This unit focuses on measurement concepts including length, area, capacity/volume, weight, angles (time) temperature,and data/graphs.
