Simple and Compount Interest Fill in the Blanks and SI extension (with answers)

The two resources with the answers are available.
The resource 1 is Simple and Compound Interest: Fill in the Blanks, is designed to help students compare simple and compound interest through guided practice. A great way to scaffold understanding is to have students fill in the blanks for both SI and CI, allowing them to actively work through the calculations.
Having both types of interest alongside each other helps students clearly see the differences: simple interest is based only on the principal amount, while compound interest accumulates on both the principal and the interest.
This approach encourages students to compare the two methods and strengthens their understanding of how interest works in different financial contexts.
The resource 2 is Simple Interest extension problems for finding the amount of years and the interest rate with 2 worked examples, 2 problems each and a challenging task.
Both resources include answers and are formatted on A5-sized sheets, with two worksheets printed on each A4 page, making it convenient for classroom use.
