🔢 Grade 7 Math: how to help at home

What each unit covers

1. 🧮Divisibility Rules

   Children use the digits of a number to tell whether it divides evenly, and explain why no number can be divided by 0.

2. 🌡️Add & Subtract Integers

   Adding and subtracting positive and negative numbers with number lines, temperatures and elevations, including the idea that subtracting a number is the same as adding its opposite.

3. 🍕Fractions

   Adding and subtracting fractions with different denominators, and multiplying and dividing a fraction by a fraction.

4. 🧮Decimal Operations

   All four operations with decimals, estimating to check answers, ordering decimals, and money problems such as unit prices.

5. 💯Fractions, Decimals & Percents

   Moving between fractions, decimals (including repeating decimals) and percents, finding a percent of a number, and simplifying and scaling ratios.

6. 🏷️Tax, Tips & Discounts

   Everyday money percents: sale prices, sales tax (with the rates given), restaurant tips, comparing deals and simple interest on savings.

7. ⚖️Expressions & Equations

   Children tell an expression from an equation, evaluate expressions, and solve equations by doing the same thing to both sides.

8. ⚖️Two-Step Equations

   Solving equations like 3x + 5 = 26 by undoing each step on both sides, writing equations from word problems and checking solutions.

9. 📈Linear Relations

   Finding the rule behind growing patterns, writing expressions like 3n + 2, and connecting tables, graphs and real situations such as rental costs.

10. ⭕Circles

    Using radius, diameter and π (about 3.14) to find the distance around a circle and the area inside it, including real objects like wheels and pizzas.

11. 📐Area & Constructions

    Area of triangles and parallelograms using base and height, and the vocabulary of perpendicular and parallel lines and bisectors.

12. 🗺️Coordinates & Transformations

    Reading and plotting points in all four quadrants, and describing translations, reflections, 180° rotations and combinations of them.

13. 🥧Circle Graphs

    Reading and building circle graphs: turning percents into numbers of people and sector angles (out of 360°), and comparing categories.

14. 🎲Probability

    Listing outcomes of two independent events (like a coin and a die), finding theoretical probabilities by multiplying, and comparing them with experimental results.
