"TURN AROUND" FACTS

Fact families

Students will step up to recite related math facts with this whole-group activity. Prepare a set of flash cards so there is a multiplication card and a division card from the same fact family for each pair of students. Distribute a card to each student; then have the class stand and form a circle. Select a student to step into the circle, read aloud his math fact, and provide the answer. Then have him turn around to show his card to the rest of the group. The student with the related fact card steps forward and repeats the process. The students step back in line and the activity continues until all the facts have been matched.

GUESSWORK

Estimation

At the beginning of each week, count a quantity of similar items and place them in a clear container. Then provide time for students to write on a slip of paper their names and estimates of how many items are in the container. Collect the papers, record estimates and the actual number of items on chart paper, and display the results near the container. Later in the week, have students solve a story problem that uses the displayed results. For additional challenges, ask students to create their own story problems or make graphs about the estimates.
