Learn how to measure length, surface coverage, and capacity in everyday situations. You'll build confidence calculating perimeter, circumference, area, and volume while solving practical real-world problems.
You will learn what perimeter, area, and volume actually describe, when each one matters in everyday life, and how to label measurements with the right kind of unit. By the end, you can look at a real situation and decide which measurement you need.
You’ll learn how to calculate the perimeter of common two-dimensional shapes and the circumference of circles using whole numbers and decimals. By the end, you’ll be able to determine total boundary lengths in practical situations like fencing, framing, edging, and measuring around circular objects.
You’ll learn how to calculate the area of squares, rectangles, triangles, circles, and composite shapes by breaking larger surfaces into simpler pieces. By the end, you’ll be able to determine how much tile, paint, or fabric a familiar surface requires.
You’ll learn how to calculate the volume of cubes, rectangular prisms, and cylinders using the idea that volume measures filled space. By the end, you’ll be able to determine the capacity of familiar objects like storage boxes, tanks, and cylindrical containers.
I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
