Four rounds include practice solving quadratic word problems in context with area problems and vertical motion problems.
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 or as a review. The discussion and collaboration in the small groups enhance the students’ learning.
The answer key for the teacher is included.
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
CCSS: Understand the concept of a function and use function notation.
HSF.IF.A.2 Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
CCSS: Solve equations and inequalities in one variable.
HSA.REI.B.4 Solve quadratic equations in one variable.
HSA.REI.B.4b Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
CCSS: Analyze functions using different representations.
HSF.IF.C.8a Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.
