1) The document is notes from lesson 58 in math class. It includes an assignment that is due on Monday January 27th and mentions an extra credit test. 2) The warm-up questions involve probability, analyzing data from team scores, using a ratio box, and writing fractions as decimals and percentages. 3) The lesson defines reflective symmetry as when a figure can be divided into two mirror images along a line, line of symmetry as the line that divides a figure into two halves that are mirror images, and rotational symmetry as when a figure matches itself two or more times in a full rotation.

Lesson 58 Warm-Up
What is the probability of rolling a composite
1)
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.

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
