 Outcome N6.5: Demonstrate understanding of percent (limited to whole numbers to 100) concretely, pictorially, and symbolically. Indicators: Observe and describe examples of percents (whole numbered to 100) relevant to self, family, or community, represent the percent concretely or pictorially (possibly physically), and explain what the percent tells about the context in which it is being used. Create and explain representations (concrete, visual, or both) that establish relationships between whole number percents to 100, fractions, and decimals. Write the percent modeled within a concrete or pictorial representation. Describe a situation in which 0% or 100% might be stated.

Lesson Preparation:

Equipment/materials:

• One copy of a beading example for each group of students. (Appendix 1.)
• One copy of the 100 bead, 50 bead and 25 bead window for each group. (Appendix 2.)
• One copy of activity sheet 1 for each student.
• Graph paper
• One copy of activity sheet 2 for each student.
• Markers or pencil crayons.

• Read the background information on beads.
• Instructions for producing copies of the beading examples and windows.

#### Activity Sheet 2

Outline a 10 by 10 region on the graph paper.

1. Using one marker or pencil crayon shade 50% of the squares in your outlined region? You may use any pattern you choose.

2. Using a marker or pencil crayon of a different colour shade 30% of the squares in your outline region? You may use any pattern you choose.

3. Using a marker or pencil crayon of a third colour shade the remaining squares. What percentage of the squares are shaded in the third colour?

Percentage: ________________

Outline a 10 by 5 region on the graph paper.

1. Using one marker or pencil crayon shade 30% of the squares in your outlined region? You may use any pattern you choose.

2. Using a marker or pencil crayon of a different colour shade 60% of the squares in your outline region? You may use any pattern you choose.

3. Using a marker or pencil crayon of a third colour shade the remaining squares. What percentage of the squares are shaded in the third colour?

Percentage: ________________

Outline a 5 by 5 region on the graph paper.

1. Using one marker or pencil crayon shade 40% of the squares in your outlined region? You may use any pattern you choose.

2. Using a marker or pencil crayon of a different colour shade 36% of the squares in your outline region? You may use any pattern you choose.
