Learning Objectives
Students will interpret numerical expressions without solving them and write simple expressions.
Introduction
(5 minutes)- Review the commutative property of multiplication and the order of operations.
- Teach students that expressions are a series of numbers and symbols, such as +, -, x, and ÷, without an equal sign.
- Write the expression 5 (4 + 3) on the board.
- Tell students that when that expression is worked out it is called an evaluation of the expression.
- The expression equals 35, therefore 5 (4 + 3)= 35 is the equation.
- Tell students that the expression 5 (4 + 3) is 5 times larger than the expression (4 + 3).
- Let students know that today they are going to evaluate the relationship between expressions and write their own expressions to evaluate.
Beginning
- Allow students to use their home language (L1) or new language (L2) in their discussions.
- Define words, such as "commutative property," "order of operations," etc.
- Have them state the definitions in their L1 or L2.
Intermediate
- Write the academic language they can use throughout the lesson on the board as you introduce the language (e.g., "commutative property," "order of operations," "double," "times," "half," etc.).
- Have students rephrase some of the definitions and draw a visual to represent new terms.
