This is a double set of task cards designed to support Common Core 6.EE.2. These cards include practice writing algebraic expressions, finding equivalent algebraic expressions (basic, 1-variable), and evaluating expressions using substitution. Exponents are used on some cards, but all expressions use positive whole numbers (no fractions, no negatives). In both sets of cards, some questions have multiple answers which increases the difficulty. The format for division includes the fractional representation.
Set one focuses on finding the mathematical form of an expression (double a number is 2n), and on finding equivalence between expressions, both with and without actually solving for an answer. There are 32 cards (8 per page). A recording sheet and answer key are included.
Set 2 includes practice with evaluating expressions when given a value for the variable. All are single-variable equations, and the questions formats are varied. Some are presented as equalities and others as inequalities. There are 32 cards in this set also (8 per page). A recording sheet and answer key are included.
This file is a 12-page PDF. The task cards make up 8 pages, and the other 4 are the two recording sheets and the 2 answer keys.
I started using task cards a fair amount last year in math, and I really like the way it allows me to circulate and talk to the kids about their thinking. I typically make multiple sets of the cards and partner the kids up. They work together through the cards, and it encouraged them to talk more about the math. I had a number of kids who were reluctant to take a risk by sharing ideas in math, and I felt this really helped them build confidence. My students enjoyed working with a partner and being able to control their pacing. It also made it easy to send home work for an absent student. These could also easily work in a math center.
