Students combine imagination, block manipulation, and computer applets to investigate fractions.

Students solve basic multiplication or addition facts using a calculator and product cards. They draw a card, read the sum or product, and press single digits on the calculator to display the number on the card.

Fifth graders engage in a tasty lesson which assist them with proportional measurements. They use a given recipe written for 12 servings, and use a chart to determine the ingredient amounts for 30 servings (or number of students in class).

Second graders, in pairs, use arrays to explore the relationship between multiplication and division.

Third graders, in groups, subtract integers by following Cherries are Positive, Lemons are Negative. They discover the rules for subtracting integers by using cherry heads and lemon heads.
