Summary

Students create a multiplication table using the example of armadillo litters.

Background:

An interesting fact about armadillos is that they have litters of four babies. The babies develop from the same egg and are quadruplets. Use multiplication facts to predict how many babies a female armadillo will have had in all after 5 litters. After 8 litters? After 12 litters? (Hint: Find the pattern and complete the chart below.) Answers are filled in.

Skills:

Mathematics: Multiplication (Table of Fours), Numerical Patterns, Multiples of 4

Materials:

Procedure:

  1. Discuss the information about armadillos above.
  2. Give each student a copy of the student activity page. (Listing the multiplication facts can be optional; it might help some students see the number pattern in the chart.)
  3. Have students complete the paper and pencil activity.
  4. Answers may be graded and discussed in class. (Hint: Mention that the multiplication facts show multiples of four. Armadillo litters always add up to a multiple of four, because they have four babies at a time.)
# Of Litter(s) # Of Babies Total # of Babies in All Multiplication Fact
1 4 4 1 x 4 = 4
2 4 8 2 x 4 = 8
3 4 12 3 x 4 = 12
4 4 16 4 x 4 = 16
5 4 20 5 x 4 = 20
6 4 24 6 x 4 = 24
7 4 28 7 x 4 = 28
8 4 32 8 x 4 = 32
9 4 36 9 x 4 = 36
10 4 40 10 x 4 = 40
11 4 44 11 x 4 = 44
12 4 48 12 x 4 = 48

Additional Activity:

Have students brainstorm other things that equal four. (Example: 2 pairs of socks)
