Percentages increase and decrease

Math

• The student has learned how to calculate percentage increase and decrease using the formula (change/original) x 100.
• They have practiced converting percentages to decimals and vice versa.
• The activity has reinforced the concept of finding the original amount when the percentage increase or decrease is given.
• They have solved real-life word problems involving percentage increase and decrease.

Continued development can include creating scenarios where students have to calculate percentage increases and decreases in everyday situations, such as shopping discounts or sales tax calculations. Encouraging students to come up with their own word problems and challenging their peers to solve them can also be a fun way to reinforce the concepts.
