What's one more app? After reviewing how to calculate missing side lengths or angle measures in a right triangle, pupils create instructions for a phone app to do all of the tedious work. They must consider all nine cases of known...

Students measure irregularly shaped bones, once using a variety of measurement methods and tools, and then again using standard conventions and metric tape measures. They explore firsthand that standardizing data collection makes...

Third graders create a shipping box from a cardboard material. In this measuring lesson, 3rd graders read the book Henry's Freedom Box and discuss the main idea. In the story a slave ships himself to freedom and the students measure and...

A great resource for any math teacher covering multiples, factors or square roots; this worksheet walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually increase...

Students identify units of measurement. In this measurement instructional activity, students predict the length and width of their hands and feet. Students discuss their findings and if their predictions were correct.

Pupils explore the midsegment of a triangle in the geometry instructional activity. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the...

Second graders use a meter tape to compare the length of the Mayflower to a basketball court and make homemade butter for crackers. Afterward, all students sit inside the makeshift Mayflower's dimensions and enjoy their Pilgrim butter.

Second graders determine the correct unit of measure to use for different situations. In this measuring lesson, 2nd graders are introduced to different unit of measure. Students study the origin of measurement and practice measuring....

Third graders examine the non-standard method of measurement and compare it to the metric system of measurement. In this introductory module lesson, 3rd graders discover the scientific observation. Students also develop communication...

Young scholars review estimation, measurement, fractions, decimals while familiarizing themselves with a new classroom at the beginning of the year.

Learners follow detailed directions to create triangles on their graphing calculator. In this properties of triangles lesson, they will create triangles on their calculators using the Cabri Jr. application. They then identify three...

Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a...

Medians, midsegments, altitudes, oh my! Pupils study the properties of the median of a triangle, initially examining a proof utilizing midsegments to determine the length ratio of a median. They then use the information to find missing...

Students complete Part A: Dissecting a Circle. They generate their own chords within the circle. Students measure the various parts of the arc in the shot put pit. The first two measurements, the chord and distance from the midpoint of...

Breaking the law in math doesn't get you jail time, but it does get you a wrong answer! After developing the Law of Sines and Cosines in lesson 33 of 36, the resource asks learners to apply the laws to different situations. Pupils must...

Discover the result of a sequence of rotations about different centers. Pupils perform rotations to examine the patterns. They also describe the sequence of rotations that performed to reach a desired result in the ninth installment in a...

Identifying and verifying reproducible patterns in mathematics is an essential skill. Mathematicians identify the relationship of sides when an angle is bisected in a triangle. Once the pupils determine the relationship, they prove it to...

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

A few good questions move this lesson right along. Young mathematicians use critical-thinking skills as they learn how to determine the perimeter of various shapes. They determine perimeter first by measuring and adding the lengths of...

While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...
