Perform this activity in an open outdoor area. Instruct students on how to throw the softball like a shot put. Place students into groups of four, and give each group one softball, a tape measure, one sheet of paper and a pencil. Allow kids to take some practice throws, then take turns throwing the ball for scoring. After each throw, the rest of the group measures the distance it traveled and records it on the paper. When all the kids in the group have thrown, instruct them to calculate their group's total distance, then divide by the number of students to find their group's average.
Give each student an index card with a number on it. Post plus, minus, division and multiplication symbols at the front of the room and tell the kids they can use them as needed. Then call out the sum of a math problem. Students must scramble to find other students holding numbers that factor with their numbers to achieve the correct answer. Have groups line up in order to display the math problem. Give out prizes for the problem that uses the most students or is the most difficult to arrange.
Make a worksheet of fraction problems, but leave one fraction missing in each equation. Write these missing fractions on index cards and hide them around the classroom. Pair each student with a partner and pass out worksheets. Include clues on where to find the missing fraction for each problem, such as "look near the biggest window." Once students find the missing fraction, they go back to their desks and solve the problems individually or together.
Discuss and display the different types of polygons and their names. Put out an assortment of construction paper in different colors, and make sure each child has scissors, a glue stick and a marker for writing. Instruct kids to make monsters by cutting out and combining several polygons, preferably one of each of the displayed shapes. Have them label each polygon with its proper name, but do not allow kids to draw anything else on their monsters. Then have students write a story about their monsters.
