Topic	Intro to Percentages
Grade level	8
PLO	A3 demonstrate an understanding of percents greater than or equal to 0%
Objective	Students will be able to use the given percentage to find the required information. Students will be able to find percentage of two given whole numbers. Students will have the understanding of the percentage sign.
Materials	White board and marker. Lifespan cards.
Prior Knowledge	Students know division and multiplication.
Intro/Hook	4 mins	Percentage sign %, no calculations here. Discuss how many pennies make up a dollar. (nickels, dimes, quarters). Each group still represents one dollar. On the board, draw out a circle representing a dollar and then fill in 25% to represent 1 quarter.
Development	4 mins	Finding a percent of any number with respect to another number (comparative number) Here percent represent the fraction with denominator 100,While the number represent the amount. Example1 -  if i have 40  halloween  candies ,i gave  10 % of candies to my son ,then what is the number of  candies i gave to my son? Solution- Here, 40 is comparative number    10% of 40 candies = 10/100* 40 =  4 candies to my son Example 2-   If i have 40 halloween candies ,i gave 10 to my daughter,then what is the percentage of the candies i gave to my daughter? Solution-       10/40*100 =25 % of  the total number of candies to my daughter
Activity	3 mins	-Give each student a “Lifespan” card - Ask them to fill out the blanks on the card, their age etc - Explain the question on the card and tell them to do their calculations on the back of the card - let the students work in pairs of two for 2 minutes - go around and make sure everyone's clear on the activity
Closure	1 min	go over the idea of percentage and how it can be used in daily life. For ex: at the shopping mall, calculating the time you have left before you have to get ready for school or dividing your food into portions and eat a certain percentage at a time. It becomes very easy to picture what's gone and what's left if you convert things into percentage.

• provide a context where a percent may be more than 100% or between 0% and 1%
• represent a given fractional percent using grid paper represent a given percent greater than 100 using grid paper
• determine the percent represented by a given shaded region on a grid, and record it in decimal, fractional, and percent form
• express a given percent in decimal or fractional form
• express a given decimal in percent or fractional form
• express a given fraction in decimal or percent form
• solve a given problem involving percents solve a given problem involving combined percents (e.g., addition of percents, such as GST + PST)
• solve a given problem that involves finding the percent of a percent (e.g., A population increased by 10% one year and then 15% the next year. Explain why there was not a 25% increase in population over the two years.)
