Partial Products
Third graders study partial-products algorithms. In this math lesson, 3rd graders use an algorithm to find the product of factors. Students discuss the relationships between multiplication and division.
Curated OER
Measurement and Estimation
Third graders create a table in order to record estimations and measurements of objects. In this estimation and measurement lesson plan, 3rd graders estimate and measure object's lengths, area, weight, and capacity.
Curated OER
Estimate Quotients and Check Division With Multiplication
Students explore how to estimate quotients and check their division with multiplication. They practice rounding the divisor and the dividend. Students compare the estimate to the exact answer and determine if it is reasonable.
Curated OER
Estimation
Students complete computer activities about estimating if items are more or less than a given amount. For this estimation lesson plan, students also estimate measurements around the classroom.
Curated OER
Classifying and Measuring Angles
Fifth graders explore the three types of angles. In this math lesson, 5th graders estimate the measure of angles and draw the angles using a protractor.
