Overview
Students read and discuss the Summary, which reviews the
main concepts covered in this section. They then describe
two ways to determine whether or not a given number is super-even.
Lastly, students are asked to set up a tournament for a
super-even number of players.
Planning
You may want to use problem 22 as an assessment.
It will show students' understanding of super-even numbers.
Students may work individually or in pairs of problems 22
and 23. After students complete Section C, you may
assign appropriate activities from the Try This! section,
located on pages 39-42 of the Student Book, for homework.

Informal
Assessment This problem assesses students' ability
to reason about patterns using pairing; symmetry; even,
odd, and super-even numbers; symbols; and directions.
The Extension below can also be used to assess this
goal. It may also be assigned as homework. |
Extension
Ask students to investigate the following statements:
The
sum of two super-even numbers is super-even. [The statements
is not true. For example, the sum of 4 and 8 is 12. Although
4 and 8 are super-even, 12 is not.]
The
sum of two equal super-even numbers is super-even. [This
statements is true. Adding a super-even number to itself
results in the next super-even umber. For example, 4 + 4
= 8, and 8 + 8 = 16.]
Allow
students to investigate the statements using number examples
and have them write down how they determined their answers
