Scholars first investigate relationships in the side lengths of 30°-60°-90° triangles and 45°-45°-90° triangles. This knowledge then helps them solve problems later in the lesson about special right triangles.

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

Classmates create a scale drawing from another scale drawing, changing the scale in the process. Groups enlarge or reduce the scale of the drawing and discuss their processes.

What's that buzzing in your ear? An insightful lesson about genetically modified mosquitoes! Partnered pupils explore the creation, release, and monitoring of mosquitoes designed to reduce the mosquito population. After watching a video,...

Insects threaten the food production industry, and aphids are one of the big players! Analyzing data of aphid populations gives insight into their behaviors. Learners model the population data of an uninhibited population with an...

Ahoy there! A fun computer science lesson challenges pupils to write a program that creates an ocean wave. They then develop stories to accompany their projects. All of this takes place within the Scratch coding program.

Introduce the inverse matrix method to solve systems of linear equations both algebraically and graphically. Using given data, your class checks their answers with graphing calculators. Handouts are included in this well-thought out lesson.
