Looking to challenge your students that have mastered basic triangle congruence proofs? A collection of proofs employ previously learned definitions, theorems, and properties. Pupils draw on their past experiences with proofs to...

Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.

Build upon the Pythagorean Theorem with the Law of Cosines. The 10th part of a 16-part series introduces the Law of Cosines. Class members use the the geometric representation of the Pythagorean Theorem to develop a proof of the Law of...

Approach the lesson from the right angle. A discussion-based lesson leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn how to name them. The lesson is...

It's not just any circle—it's the unit circle. The fourth activity in the series is an introduction to the famous unit circle. While working through a series of activities, young scholars learn the components of the unit circle and how...

It's all relatively simple once you get the gist. Young mathematicians learn about sample spaces and simple probability by conducting an activity with dice. To complete the second of six parts in the Statistics and Probability unit, they...

A fun, engaging lesson is definitely in the cards for your future. Pupils explore a deck of playing cards in the fifth of six parts in the Statistics and Probability series to learn about its suits and the number of each card type. They...

Turn your math lesson into a carnival game with this fun, outdoor activity. After reviewing the concept your class will be practicing briefly, split your class up into teams and head outdoors. These teams work to solve math questions and...

Practice counting in patterns and skip counting by 1, 5, and 10. Once the patterns have been taught, teams of 5 or 6 learners -- holding hands in circles -- skip count each time they collectively bounce a balloon up into the air. Early...

Examine how addition, subtraction, multiplication, and division relate to and are separate from each other. As they listen to the book, The Doorbell Rang, they demonstrate the math described in the story by cutting up paper cookies...

Get those kids practicing basic math skills. They practice adding 3 numbers together by playing the game "Triple Addition Shuffle." Each pair of learners shuffles number cards together, places them face down, then flips them over to...
