Each of the four included resources have 12 question and answer cards (for a total of 48) that can be used in a variety of ways. There is also a worksheet of the same questions. The worksheet format is beneficial for students that may be absent or called out of class during this activity.

Suggestions for incorporating these cards in your instruction:

The 48 cards/questions can be individually presented to students on cards. For each question there is a matching answer card. Students can match the question with the answer or start with the answer and find the question.

OR use the worksheet with all twelve questions and have students respond to each question without an answer choice. The worksheet also provides an alternate assignment for absent students or those students that are out of class when you do the activity.

H.O.T. *Challenge; Give students an answer card and ask for a question to match the answer. This requires a complete understanding of the concept and moves the student to think on a higher level than is normally assessed.

3 options for recording answers. Multiple copies are on each page, print only what is needed for your class size.

An answer sheet is included and a solutions page for the worksheet (same problems as those on the cards).

Suggested activities:

Scavenger Hunt: Place answers around the room. Hand out a question, challenge students to find the answer.
Match-Up Challenge; Working in teams, students ‘race’ to find all the matches.
Speed-Math - Set-up like speed-dating where each student is an expert on one card and sits across from an ‘intern.’ They swap cards and share answers, instructing when necessary.
Scoot or some version of it
Quick Review or Warm-up to keep skills alive.

This is just one of many resources in the series to cover skills for Algebra 2.

These resources are great for differentiation, diagnostics, review and assessment.
