Term 1 Week 7 · Place value in a 3-digit number · CG Quarter 1, competency 10
| # | The misconception | Where it shows | What to do |
|---|---|---|---|
| 1 | "The value of the 7 is seven" | Bundled sticks. "How many sticks in seven bundles?" | |
| 2 | "The value of the 7 is tens" | The value is a number; the place is a name. Write both | |
| 3 | The zero can be rubbed out | Day 3. Do not mention it today — the surprise is the teaching | |
| 4 | Digit and value are the same | Right in the ones, wrong elsewhere. §C.3's last question | |
| 5 | Reading aloud instead of understanding | Ask for one digit's value, never the whole number | |
| 6 | The leftmost place is always hundreds | Count from the right: ones, tens, hundreds | |
| 7 | A bigger digit means a bigger value | In 472 the 4 is worth 400 and the 7 is worth 70 |
