Update: This Lesson Is Part of Book 3 of Doodles Do Algebra: “The Basic Math of Algebra” available on Amazon.
Available in the book, “The Basic Math of Algebra, Book 3 of Doodles Do Algebra“
Today’s lesson is a brief review of what your child has learned over the last weeks, as well as a review of basic arithmetic.
It should be a gentle reminder of properties of numbers that he will be using in earnest in the weeks to come.
- 1 (coefficient is the number accompanying the xy term, in this case it is 1. If the question were 2xy, the coefficient would be 2)
- 30 (negative times and negative is a positive)
- -10 (positive times, or divided by, a negative is a negative)
- -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, or any integer bigger. (remember whole numbers are positive only and integers are positive and negative whole numbers)
Thanks and have a great weekend!
