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.

On Tuesdays I upload an update of what we did in math for the week.

RightStart Geometry:

Lesson 84 Rotating

The lesson explains what rotation means in a mathematical sense, then has the student draw various rotations.

On one hand, the directions say to “measure only the 2.5 cm line,” deriving the rest of the lines and angles from your knowledge of how to draw geometric figures. On the other hand, the directions say to “construct every line accurately. Don’t guess.” Well. Tears of frustration ensue during the final rotation, which for some reason is wonky. I know the feeling from various projects I’ve done.

I am not allowed to help. I think she’s caught on that it takes me awhile to get up to speed on these lessons, as she’s journeying to places I either haven’t been for a long time, or perhaps never visited before. It occurs to me that it would’ve been a good idea to go through all the lessons myself a bit ahead of her.
