Place Value Play this 3rd grade math lesson

Understanding place value is essential to developing number sense and strategies for computation. DreamBox uses the context of packing groups (pallets of 1,000, cases of 100, and boxes of 10) to introduce the idea that in numerals, “place determines value.” Students experiment with packing and unpacking in a variety of situations.

Multiplication Area Models Play this 3rd grade math lesson

DreamBox uses area models to help develop multiplicative thinking. In a series of activities, a given rectangle is covered using smaller rectangles. As grid lines are removed, students work with open arrays. As rectangles are moved, students are exploring the big ideas in multiplication: distributive, associative, and commutative properties.

Building and Comparing Fractions Play this 3rd grade math lesson

Building and Comparing Fractions

This lesson is from a series designed to ensure students understand that fractions can be used to represent the division of an object into equal-sized pieces. Students then use that understanding to compare fractions. Our virtual manipulative engages students by helping them make sense of the relative size of halves, thirds, fourths, sixths, and eighths when compared to a common whole. Conceptually, students come to realize that the more pieces into which an object is divided, the smaller each piece will be. Based on that understanding, students will know 4/4 is greater than 3/4, and 3/4 is greater than 3/5.

Placing Fractions on the Number Line Play this 3rd grade math lesson

Placing Fractions on the Number Line

An understanding of fractions as real numbers with value and magnitude is fundamental to understanding the nature of fractions as well as how to perform fraction operations. This lesson engages students in actively placing fractions in their correct location on the number line. A number line representation ensures students understand how to compare and order fractions apart from any specific part-whole context. Instead of using a particular context—such as dividing an object into three equal parts—students use landmark fractions and numbers to place fractions on a number line from 0 to 1 and from 0 to 2.
