Triangle Area = Half of Corresponding Rectangle (Prime and Composite Areas) (K-2nd Grade)(Tuesday-Friday only; not Monday classes)

Last week we explored the area of rectangles by looking at the multiplication of dimensions. It is only logical to extend this lesson to looking at the area of each rectangles corresponding triangle as exactly one half.

Scrabble Algebraic Method, Ascending and Most Frequent Value

Last week, I introduced how mathematicians use algebraic symbols to represent numbers. We used the ascending value method where A=1, B=2, C=3 …. Z=26. One way to connect language and math is to have children convert words to numbers using several different letter valuation methods. The children were asked to add the value of each letter.

Algebraic expressions are letters that we assign to unknown values or to specific values.
