After learning about Numbers, Grade 4 students learn about Triangles. They need to identify the types of triangle, draw the triangles based on given dimension, and describe the properties of triangle.

For the tuning in activity, students work in group and cut straws with three different colors into three different lines. Then, they need to stick any three lines to form any triangles. After that, they categorize them into the correct type of triangle.

Next learning experience is draw triangles. Students need to draw triangles using a compass and ruler. They might be drawing isosceles triangles, equilateral triangles, or scalene triangles. They are very excited since this is their first time to use compass. They even ask teachers for homework. Great!
