How to learn maths without fear. 12 lessons.

1. Why maths is not a monster Maths is a muscle, not a talent. You train it in small bits, and it counts things you care about. ⏱ 13 minutes Practice
2. A mistake is a clue, not shame A wrong answer shows you exactly where to look. Who rubs a mistake out throws the clue away. ⏱ 14 minutes Practice
3. Paper and pencil always at hand The head thinks, the paper remembers. How to set up a counting workspace and write a method you can read. ⏱ 14 minutes Practice
4. Calculator: when yes, when no A calculator is a tool like a saw. Great for huge numbers and a check, bad for learning the basics. ⏱ 13 minutes Practice
5. Short and often: 10 minutes a day Ten minutes a day beats an hour once a week. How to build a small practice that lasts. ⏱ 14 minutes Practice
6. How the worksheet works On one page you see all the questions at once. Like a notebook. A tick on each one, or Check all. ⏱ 15 minutes Practice
7. Estimate the answer before you count An estimate is a safety net: a rough answer in advance that catches nonsense before you hand it in. ⏱ 14 minutes Practice
8. Check: test your answer Every calculation can be run backwards. A check takes twenty seconds and catches mistakes an estimate does not see. ⏱ 14 minutes Practice
9. Word problem: read twice A word problem is a story with a hidden question. First reading for the story, second with a pencil for the numbers and the question. ⏱ 15 minutes Practice
10. Draw it Marks, a number line and strips: three quick pictures that turn a tangled problem into a clear one. ⏱ 14 minutes Practice
11. Maths around us The shop, the kitchen, clocks and the playground are a free practice book. How to notice numbers around you and count them. ⏱ 14 minutes Practice
12. 准备课 finale: your practice plan All ten tools on one pile and a weekly plan you take into the next levels of the course. ⏱ 16 minutes Practice
