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 85 making Wheel Designs

As it says in the book, this is similar to Lesson 114 in Level E. Kid1 noticed some nuance of variation.

Lesson 86 Identifying Relfections and Rotations

We are hitting a segment of lessons which are done quietly, with a simple, “well, that was easy,” as the books are reshelved. Really, I don’t have much to say except that they’re easy. If math is a struggle, look to this segment as a breather.

Lesson 87 Translations

“Translation is the mathematical name for slide.” Still in the easy segment, folks.

Lesson 88 Transformations

The worksheet reminds me of something out of a book of drawing lessons, but Kid1 comments that if it were drawing the figures would be slightly flattened (due to perspective and vanishing points, although she doesn’t use those words).

The materials list leaves out a couple of items the student will need. Other than than, very straight forward.

Lesson 89 Double Reflections

The only reason she isn’t flying through these lessons is that she’s taken to reading comic books on the side while she’s working them.

Lesson 90 Finding the Line of Reflection

Worksheet question: “Connect each point of the triangle with its corresponding image using a dotted line. Then construct the perpendicular bisector of each line. What do you observe?” Answer I find written on worksheet: “That this is a lot easier and more fun than I thought it would be.” Verbal comment: “It’s so obvious that it’s going to be the line of reflection that it isn’t worth saying that.”
