Skip Counting and Multiplication

In this activity, students color in hundred charts (or, in this case, a 0-99 chart) as they count by twos, threes, etc. Students notice different patterns. Why are all of the twos in columns? Why are the fives in two columns and the tens in one column? Why does the nines table look like a staircase? Predict what the zero table would look like. Predict what the ones table would look like. Predict what the 11s table would look like. By noticing patterns in multiples, students improve their basic facts.

Common Multiples

The multiples of three and four were completed on transparencies and the multiples were colored in with permanent marker. When the threes and fours are placed on top of each other, the common multiples are 12, 24, 36, 48, 60, 72, 84 and 96. Students are able to visualize what a common multiple is and what the least common multiple is.

The least common multiple of 5 and 7 is 35. Another common multiple is 70.
