With a mathrack virtual manipulative, students learn that you can build the same number in several different ways, e.g. 10+3 = 7+6. Students can use a variety of strategies to solve these problems, including the commutative property (10+4 = 4+10), doubles or near doubles (10+4 = 7+7), and more.
Early learners often struggle to “wrap” or move to the next row on a hundreds chart. The distance between numbers can be hard to grasp. For example, the number 30 is just one space away from 40 on a hundreds chart.
Turn hard problems into “friendlier” problems by making one of the addends a multiple of 10. Students start with smaller 2-digit addends, and when they’re ready they use 3-digit addends. It’s an efficient mental math strategy.
Students create shapes with a specific side length, then measure the other sides using a ruler. They construct triangles, quadrilaterals, and polygons, and use a ruler to measure their sides.
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 explore ideas in multiplication: distributive, associative, and commutative properties.
Students create a specific type of triangle, utilizing knowledge from previous game set. Students construct different types of triangles, quadrilaterals, and polygons, using a ruler and protractor to measure side lengths and angles.
This lesson helps students think conceptually, not procedurally, about subtracting fractions by using the “removal” or “take away” strategy. This enables skill of subtracting mixed numbers and improper fractions fluently, mentally, and easily.
Students use the order of operations to evaluate expressions involving addition, subtraction, multiplication and division.
Students are given a shape with marked angles and side lengths, then asked to create a new shape using scale factor by constructing different types of triangles, quadrilaterals, regular polygons, and scaled polygons.
Students use the order of operations to evaluate integer expressions involving addition, subtraction, multiplication and division.
Students deepen understanding of angle measurement and rotation while fluently reasoning about and using supplementary and vertical angle relationships. Students use deductive reasoning to make rotations, aim for targets, and determine angle measurements.
