Measurement, Perimeter and Area

Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.

Learners construct their understanding of measurement and dimensions in this step-by-step approach that begins with an all group vocabulary introduction, consisting of measuring objects and dialoging using measurement vocabulary....

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

Having a good working knowledge of math vocabulary is especially important for geometry learners. Here are 119 pages worth of wonderfully constructed definitions, constructions, formulas, properties, theorems, and postulates. This is a...

Should the standard deviation be used for all distributions? Pupils know that the median is a better description of the center for skewed distributions; therefore, they will need a variability measure about the median for those...

Apply, apply, apply! A measurement lesson applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method that...

Using an installment from the Math at the Core series, pupils learn about Kapa cloth, which is made from bark. The video shows how much cloth one cup of bark makes. Then classmates, working in pairs, determine the number of cups of bark...

After viewing a short video about a climb up Mount Everest, high schoolers read about triangulation for measuring distant elevations. Have your class work in groups to construct an inclinometer and then use it to measure the height of...

Learners calculate the size of a mummy case and its contents using ancient Egyptian measurements.
