Today we’ll be doing a very simple construction — bisecting a segment. Â In other words, we will be cutting a line segment in half. Â Begin by drawing matching circles from your two endpoints (A and B). Â The radius of the

Identify Geometric Shapes
Here’s a little activity to wrap up our geometry study for the week. Â Have your students consider the following drawing and try to identify as many polygons as they can. Â If they need a little guidance, here are some possibilities…
Copy Any Polygon
We can employ the two skills we’ve been working on this week — constructing congruent segments and constructing congruent angles — to create a copy of any polygon. Use a straight edge to draw any polygon. Â Here’s an irregular hexagon
Construct Congruent Angles
Today we’ll be looking at another basic construction: congruent angles. Â You can use this construction to copy any angle without using a protractor to measure. Begin with the angle you would like to copy. Draw any ray. Â This will act
Geometric Drawing
This week, the big kids are working on their geometric constructions, mathematical drawings achieved with the use of only a compass and an unmarked straight edge. This is one of my favorite units to teach. Â Mathematics in general is an
All Aboard!
Albert Einstein said, “Play is the highest form of research.” Â This is most true when our children play with toys that allow them to create, experiment, and solve problems. Our three-year-old is enchanted with his wooden train set these days.
