How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Knowing the addition formulas allows for the calculations of double and half formulas. The fourth installment of 16 has the class use the addition formula to develop the double angle trigonometric formulas. Using the double formula,...

Create a human fraction to learn about division of exponents. Scholars develop the rule for division of exponents by being part of a human fraction to explore and justify the rule. They also consider zero exponents and negative exponents.

After learning how to convert decimals to fractions and fractions to percents, young mathematicians fill in a chart in which they convert values. Learners convert 0.50 to fraction and percent, 2/8 to a decimal and percent, and 80%...

Determine the level of understanding of decimal and fraction values within your classes with a resource that provides pupils with opportunities to practice with decimal and fraction concepts. 

Roses are red, but did you know that some are lighter while others are darker? Scholars read an infographic to decipher the fraction and percent of rose color and their country of origin. They go on to make comparisons and estimate while...

Three heads are better than one. After reading a conversation between three friends about how to compare fractions, scholars analyze and discuss each presented strategy. These include using unit fractions, using benchmark fractions,...

Fold, fold, and fold some more. In the first installment of a 35-part module, young mathematicians fold a piece of paper in half until it can not be folded any more. They use the results of this activity to develop functions for the area...

Assess pupil understanding of rational and irrational numbers with a mid-module assessment that is the 15th lesson in the 25-part series. The questions represent the objectives in the first half of the series. Topics include decimal...

Judy Clocks are a great invention. Here, learners review telling time to hour and half hour on Judy clocks, begin telling time to quarter hour, use clock stamps to practice, and play computer games using Trudy's Time and Place House...

Sometimes you can add an s to a word to form its plural. Sometimes you can't. Help your class learn how to pluralize irregular words like calf, woman, and half. After, have them study the prefixes un, de, pre, dis, and re in the colorful...

Create models to demonstrate multiplication and division of fractions. Using fraction tiles to model fractions, pupils explore fractions on a ruler and use pattern blocks to multiply and divide. They also create number lines with fractions.

Students sort and compare apples before making apple prints. In this apple lesson, students use a painting to inspire art prints made with apple halves. Students compare and sort apples.

Fourth graders become familiar with fractional parts of a ruler.  In this measurement lesson, 4th graders measure various objects to an 1/8 of an inch.   Students measure a piece of paper based on teacher direction....

Rather than a worksheet, this teacher resource is a one-page, scripted answer sheet for a guided lesson on partitioning circles and rectangles. First or second graders are asked to identify which figure shows halves. While the pupil...

Adding fractions with unlike denominators can be cloudy, but attaching the fractions to real-life math can add to fraction number sense. Alex needed to run only a mile, will completing the training in two segments satisfy this...
