🔢 Grade 8 Math: how to help at home

What each unit covers

1. 🟦Squares, Cubes & Roots

   Knowing perfect squares and cubes, finding square roots and cube roots, estimating where a square root falls between whole numbers, and linking squares to the area of a square.

2. ➖Integer Operations

   Multiplying and dividing positive and negative integers, adding and subtracting them, working with the order of operations, and solving real-life problems such as temperature changes.

3. 🍕Fraction Operations

   Adding and subtracting fractions with unlike denominators, multiplying and dividing fractions, switching between mixed numbers and improper fractions, and finding a fraction of an amount.

4. ⚖️Ratios, Rates & Proportions

   Simplifying ratios, finding missing terms in equivalent ratios, comparing unit prices, working with speed, scaling recipes and map distances, and turning a part of a whole into a percent.

5. 📈Patterns & Two-Step Equations

   Writing and evaluating expressions like 3n + 2, solving two-step equations, and finding the rule for a growing pattern or a cost made of whole items such as tickets.

6. 📈Tables, Graphs & Linear Relations

   Using an equation like y = 3x + 2 to build a table of values, find a missing x or y, and describe how the variables change together.

7. 🧮Equations with Brackets

   Solving one-variable equations, including ones with brackets and negative numbers, checking by substitution, and spotting a common mistake with the distributive property.

8. 📐Pythagorean Theorem

   Finding a missing side of a right triangle, checking whether a triangle is a right triangle, and using the theorem for ladders and diagonals.

9. 📦Nets & Views

   Matching flat nets to prisms and cylinders, working out what the parts of a net measure, and picturing an object from above, the front and the side.

10. 🧱Top, Front and Side Views

    Children picture what a building made of cubes looks like from the top, front and side, and use views to work out how many cubes it has.

11. 📦Surface Area & Volume

    Finding surface area and volume of boxes, cubes, triangular prisms and cylinders, working backwards to a missing dimension, linking cm³ to millilitres, and recognizing nets and views of 3D objects.

12. 🪞Tessellations & Transformations

    Why some shapes tessellate, naming the transformations in a tiling, and finding the image of a point after a translation, reflection, rotation or dilation on a coordinate grid.

13. 🎲Probability & Data

    Counting outcomes, finding theoretical and experimental probabilities, predicting how often something will happen, and summarizing data with the mean, median and range.

14. 🎲Independent Events

    Finding the chance that two separate events both happen, such as a coin toss and a die roll, by multiplying their probabilities.
