The Classroom Package: Related Activities and Lessons/Reading Fun
Step 1: Have each group create one math problem that
uses statistics about the rain forest or rain forest animals and requires
using the particular math skill(s) you have been learning. (See below for
some samples.)
Step 2. Have each group make a line drawing of a rain forest animal
(the animal should be different from the animal they made up the problem
about). (Alternatively, use preprinted handouts of animal linedrawings.)
Step 3: Have each group write the answer to their math problem (with
large numbers) on the animal they drew, then post the drawings on a designated
area on the wall/board.
Step 4: Copy and number the math problems created by the groups, then
distribute one copy to each group.
Step 5: Have each group solve the problems matching them with
the posted animals that have the corresponding answers. Step 6: Review the
answers and give each group one of the animal drawings to color.
Note: Aid students as they are creating their problems and check their problems for logic and accuracy. Encourage them to make their statements/problems as scientifically accurate as possible.
Sample Problems
1. A hungry birds
swoops after a tarantula and comes away with three legs. How many legs does
the tarantula have left?
2. In one minute a sloth can move four feet. How far could it move in ten
minutes?
3. 240 inches of rain fell in Limoncocha last year. At this rate, how much
rain could Limoncocha expect to get in two months? What percentage of the
total yearly rainfall would fall in one month on average?
4. A sloth is carrying 21 different species of moths and beetles in its fur.
If, on average, there are 17 of each species of moth and beetle, how many
total insects are making the sloth their home?
5. A group of 80,000 army ants is marching through the forest. If they are
marching in 160 rows, how many ants are in each row?
6. Scientists estimate that a thimble full of rich rain forest soil contains
1,004,225,000 organisms. What digit is in the ten thousands place?
