RightStart Geometry

The continuing saga of our adventures using RightStart Geometry and RightStart B. I have an 11yo and a 7yo who have average math ability.The 11yo has done Miquon, Singapore, RightStart Transitions, Level D and Level E; RightStart has saved her from a life a math phobia.

I try to update our adventures on Tuesdays, although sometimes it doesn’t get done until Wednesday. And sometimes we really haven’t done that much math, so I skip it entirely.

RightStart Geometry:

Lesson 101 Semiregular Tessellations

This is a 2-3 day lesson. It isn’t necessarily difficult, it just takes awhile to execute. It especially takes awhile when the weather suddenly becomes spring-like and we want to go outside for fresh air and sunshine.

Sidenote in the book: “If you’re finding pencil lines to be boring, here’s how to add some color to your work.” Oooh, perfect timing -- yes, it really is time to add some color. And now we have suggestions for how to use gel pens to draw tessellations. Cool.

Lesson 102 Demiregular Tessellations

What is the difference between a semiregular and demiregular tessellation? And how does the term semi-pure tessellation fit in to all of this?

Kid1 has realized that this somewhat mindless work of drawing out and coloring in tessellations can be done while listening to Jim Weiss reading Story of the World. Homeschool multi-tasking at its best! She even made extra photocopies of her tessellations so her younger sister could color some in; I think this is really clever on her part until I see that it is suggested in the book. Okay, then, it’s really clever on the author’s part. Kid2 is thrilled to be included in the “advanced math”.
