Product Description
Review multiplication and area with this versatile (and free!) set of “I Have…Who Has?” cards, designed to suit both large groups and small groups.

Common Core State Standards for Mathematics addressed:
Measurement & Data (3.MD, 4.MD)
• Multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning. (3.MD.7b)
• Apply the area and perimeter formulas for rectangles in real world and mathematical problems. (4.MD.3)

Included:
• 1 set of 32 task cards – provided as a full set and 16-card “half-sets”
• master list of question and answers

There is a full set of 32 “I Have, Who Has?” cards, two smaller, 16-card “half-sets” that use the same questions and answers as the full 32-card sets, and a master list of the questions and answer on the cards. The cards in the set have a unique question and answer, with none of the questions or answers repeated. There is no specific starting card as the 32 cards loop around. Any student can begin, and since none of the questions or answers are featured more than once, the cycle will eventually lead back to whatever student began the activity.

This set is adaptable, designed to accommodate both large and small groups. There are 32 cards in the full-set to provide enough material for large classes. You can still use the entire set even if you don’t have 32 students by having some students hold two cards at once. However, if you much fewer than 32 students and you want to get more use out of each set, I have included a pair of “half-sets” for each set of 32 cards. These half-sets contain 16 cards and are identified as Set A1 and Set A2. They have the exact same numbers and expressions from the original sets of 32, but they are split into two groups and have their “ending” cards altered so that the 16th card loops back to the 1st card and the 32nd card loops back to the 17th card. If you have a class size closer to 16, you can use a half-set, such as Set A1, doubling up cards or kids as needed if you don’t have exactly 16 kids, and use the half-set with your class one day, saving the other half-set for a different day.

In order to allow for easier separation and sorting of the cards, each full set and each half-set has its own animal icon in the upper right corner. The full set has a cow, while the 16-card half-sets have different animals, with the first half-set (Set A1) featuring a pig and the second half-set featuring a chicken. The cards are also labeled in the bottom right corner as an additional indication of what set the card belongs to – Set A, Set A1, and Set A2.

Included with the cards is a master list all the questions and answers on each of the cards. If you want to follow along with the students, you can have the student with a particular card begin, and use the master list to keep track of what card will be up next in case a student needs a hint. Alternately, you can have any child begin, and if you locate their statement and question on the sheet, you will be able to use the list to follow along in sequence.
