Lesson 58 Warm-Up

1)  What is the probability of rolling a composite
number on one toss of a number cube?

2) After 5 games, the team's average score was 88.
After 6 games their average score had increased to 90.
What was their score in the sixth game?

3) Use a ratio box. The ratio of walkers to riders was 5 to 3. If 315 were
walkers, how many were riders?

4)   Write 1/6 as a decimal.

5)   Write 1/6 as a percent.




                                                                             2
Lesson 58:

*reflective symmetry - if a figure can be divided into 2 mirror
images along a line

*line of symmetry - a line that divides a figure into 2 halves that
are mirror images of each other

*rotational symmetry - a figure that matches itself 2 or more
times in a full turn




                                                                      3
