🔢 4th grade Math: how to help at home

What each unit covers

1. 🔢Numbers to 10,000

   Reading, writing and comparing numbers up to 10,000: place value, expanded form, number lines, ordering and rounding.

2. 🔟Tenths & Decimals

   Reading, comparing, ordering and rounding decimal tenths, linking them to fractions, and adding and subtracting them.

3. 🔟Decimals

   Tenths and hundredths as decimals, linking them to fractions, placing and comparing them on number lines, and adding and subtracting decimals by lining up the decimal points.

4. ➕Add & Subtract

   Adding and subtracting numbers to 10,000 with regrouping, counting up to subtract, estimating by rounding, and solving word problems.

5. 🧮Multiply & Divide

   Multiplying and dividing 2- and 3-digit numbers by 1-digit numbers by splitting them by place value, plus remainders, estimating and word problems.

6. ✖️Times as Many

   Multiplicative comparison: reading 35 = 5 × 7 as “35 is 5 times as many as 7”, and solving “times as many” problems, which are different from “more than” problems.

7. 🍕Fractions

   Naming fractions from pictures and number lines, comparing fractions with the same top or bottom number, using 1/2 as a benchmark, and finding equal fractions.

8. 🍰Fractions

   Reading and naming fractions from halves to tenths, counting by fractions, comparing them, and seeing 3 × 1/4 as three fourths.

9. 📈Patterns & Tables

   Extending increasing and decreasing number patterns, naming pattern rules, finding rules in input/output tables, and describing how two quantities are related.

10. ⚖️Equations

    Solving one-step equations with a box or letter for the unknown, using all four operations, and matching equations to word problems.

11. 📐Angles & Area

    Sorting angles into acute, right, obtuse and straight, finding area by multiplying length by width, and working backward to find a side.

12. 🔷Polygons & Perimeter

    Telling regular polygons (all sides and angles equal) from irregular ones, finding lines of symmetry, and measuring perimeter around regular and irregular shapes.

13. 📐Triangles, Quadrilaterals & Angles

    Triangles are named by their sides (equilateral, isosceles, scalene) and by their angles (acute, right, obtuse). Quadrilaterals include squares, rectangles, rhombuses, parallelograms and trapezoids. Complementary angles add to 90° and supplementary angles add to 180°.

14. ⚖️Metric Measures

    Changing between grams and kilograms and between liters and milliliters, understanding kilo, centi and milli, and choosing a sensible unit and tool.

15. ⚖️Feet, Pounds & Gallons

    Knowing how US customary units compare (12 inches in a foot, 16 ounces in a pound, 4 quarts in a gallon) as well as metric and time units, and converting a larger unit to a smaller one.

16. 📈Line Plots & Data

    Reading tables of measurements in halves, fourths and eighths of an inch, finding differences, comparing two classes, and choosing questions that need data.

17. 🏦Expenses, Profit & Banks

    Personal financial literacy: your child tells fixed from variable expenses, works out profit, compares ways to save, plans how to split an allowance between spending, saving and sharing, and learns what banks do.
