What is the Algebra 1 “Slow It Down” Series?

The Algebra 1 “Slow It Down” Series is ideal for teachers who are looking for concentrated practice on a single skill or a limited set of skills. These work well for students who need additional focused practice to master a skill.

As part of the Algebra 1 “Slow It Down” Series, the focus of this activity is practice limited to solving quadratic equations from word problems using the area of rectangular shapes. The equations are provided using the area formula A = lw. Students are expected to solve the given equations, then use the solutions to find the dimensions of each rectangle.

Separate students into groups of four and give each student their own copy of Round 1. Students should discuss the problem as they work on it and agree on the correct answer. Once each student in the group has the correct answer, ONE person from the group takes ONE Round 1 sheet to have it checked by the teacher.

If the answer is correct, the student then picks up four copies of Round 2 for the group. If the answer is not correct, the teacher sends the student back so the group can correct Round 1.

Groups continue working until each round is completed and checked by the teacher for accuracy.

This activity works well early in a lesson when students are actively learning a new skill. The discussion and collaboration in the small groups enhance the students’ learning.

The answer key for the teacher is included.

Teacher Setup:

Print enough copies (one-sided) for each student to have his/her own. Cut pages on the dotted lines to separate rounds into separate stacks (all of Round 1 is in one stack, Round 2 is in a different stack, etc.).

After handing out Round 1, keep stacks of Round 2, Round 3, etc. and only allow students to take the next round in order when their group is ready for it.

Included in the package:

· Four relay rounds

· Answer Key for Teacher
