Young mathematicians learn how to solve problems involving stratified sampling. They review concepts of sampling and proportionality by watching a video and then they complete a worksheet of questions on this topic.

Clamp onto the resource and don't let go. Future mechanical engineers produce a pipe clamp from a sheet of metal. This idea is to use the pipe clamp to affix a pull-up bar in a doorway.

Students explore differents types of triangles and quadriaterals. In this polygon lesson plan, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Pupils recognize patterns in a numerical sequence, create new patterns and predict outcomes to established sequences.

In this conditional statements worksheet, 11th graders solve and complete 15 various types of problems. First, they determine if a conclusion can be reached from the two statements using the law of detachment or the law of syllogism....

Students solve problems by discovering the eigenvalues that satisfy design questions. They explain how relaxing a small angle approximation can change the solution. Students apply the numerical model of pendulumm motion to solve the...
