Second graders examine the relationship between addition and subtraction. In this number sense instructional activity, 2nd graders practice their computation skills and use various strategies (including manipulatives...
Curated OER
Robot Gears
Learners build simple gear trains and record data to discover how to compute gear ratios. They investigate the definition of torque and how torque can be increased or decreased in a gear train.
Curated OER
The Six Faces of Garbage
Students use the mathematics of surface area to approach the problem of garbage pollution from the classroom. After watching a video, students construct replicas of cereal boxes and compute their surface area.
Curated OER
Jelly Bean Math
Young scholars estimate, measure, compute, and create patterns using jelly beans. In small groups, they solve various calculations, place jelly beans into groups, invent a new flavor, create a pattern, and complete a worksheet.
Curated OER
Measuring Pots
Students use an activity sheet to construct analogies about possible function of ancient or historic ceramics and compute circumference from a section of a circle as they study measuring pots.
Curated OER
Buying on Credit
Students determine how buying on credit adds to the total cost of an item by computing the interest. They find a major item advertised in a magazine and identify the price. Then they identify the rate of a credit card and calculate the...
