Procedure:

Copy and cut apart one sort for each group of 4 students.

Give each group a set of cards and 4 sheets of paper labeled addition, subtraction, multiplication, division.

Have students place the cards in one pile face down on one of the desks.

Each student gets one sheet of the labeled paper.

Each student picks a card one at a time:

• One student from the group picks a card and reads while the group listens.

• Together the group decides how to solve the problem, and then places the card on that sheet of paper.

• Another student picks the second card….

• …the same process is repeated until all the cards have been placed in one of the four categories

Checking the Answers:

Optional Step—Have the students record the letters of the problems for addition, subtraction, multiplication, division on and index card and give it to you so that you can check each group’s accuracy after the lesson.

Use the PowerPoint to check the answer and help students identify the open sentence that will solve the problem.

Next Steps

Consider assigning each student or pair of students a problem to demonstrate or explain. Students can use:

• Words * A picture they have drawn * Manipulatives * Any combination of these.
