Students use a dictionary to gather appropriate information for writing simple definitions. They recognize prefixes that relate to numbers, such as mono-, bi-, and tri-. Pupils use their creative abilities to extrapolate new words to...

Students estimate and measure triangles. In this geometry lesson plan, students identify the relationship between three sides and a triangle. They use the inequality theorem to decide if a triangle will be formed or not.

Add and subtract fractions with common denominators! In this fractions instructional activity, upper graders review what they already know about fractions, use manipulatives to compare fractions, and add and subtract fractions.

Young scholars use problem-solving approaches to investigate mathematical content. They formulate problems from situations within and outside mathematics content. They warm up with a survey done by the teacher. Everyone uses practice...

Students investigate linear programming using the TI. In this algebra lesson, students collaborate and graph linear inequalities on a TI. They analyze their data and present it to the class.

Learners investigate buying purchases in bulk. In this buying in bulk instructional activity, students consider ways to cut costs and reduce waste in landfills by making bulk purchases.

Submarines are the fous of this math and science lesson. In it, learners explore the world of submarines: how they work, and what they are used for. They engage in hands-on activities, watch video clips, and work in cooperative groups in...
