Learning activities

The Learning Activities below are laid out by the sections in the Minds on Math text and the corresponding curriculum outcomes. This Unit corresponds with Chapter 1 of the text, but it is necessary to supplement (or substitute) the activities in the text in order to achieve the outcomes. These activities will need to be modified to meet the specific needs of each class. Attention to individual learning plans for pathways will need to be adhered to.

Section 1 / Section 2 / Sections 3 and 4 / Sections 5 and 6

Section 1: Rational Numbers

SCO:
A2 – Students should be able to graph, and write in symbols and in words, the solution set for equations and inequalities involving integers and other real numbers.
A4 – Students should be able to demonstrate an understanding of the interrelationships of subsets of real numbers.
A5 – Students should be able to compare and order real numbers.

Suggested Materials:
Masters 1.3, 1.7; scientific calculator

Focus: Students will learn what a rational number is. Students will compare and order rational numbers.

Activities:
- Introduce the different groups of real numbers and what the set of real numbers are.
- Present some background information on basic set theory
- Students should try to represent the difference between sets of numbers using a diagram.
- Journal activity: Give examples of how numbers satisfy the conditions of natural, whole, integer, rational and irrational numbers. See ‘Discussing the Ideas’ for more journaling ideas
- If available, use fraction kits to help students order rational numbers. Have them work in groups, and decide how they are going to signify when the fraction is negative. Have the groups present their method for assigning the negative sign to a fraction using the kits
- Do the practice exercises in the text. Do ‘odd letters’ to begin, and do the ‘even’ ones if you have trouble

Introduce the chapter project at the end of this section.
