15. Counting in Groups 135 students can be taught to use pattern blocks
to solve the problems.
What color are the snowflakes? Red.
Let’s fill the snowflakes with red pattern
blocks. How many pattern blocks do you
need to make 1 snowflake? 2.
So, by how many do the pattern blocks
increase for every snowflake? By 2.
Then, let’s say together how many pattern
blocks increase in order. 2, 4, 6, 8, 10.
How many pattern blocks are there in
total? 10 pattern blocks.
