What it shows
Strips cut into halves, thirds, quarters and smaller parts show which fractions are equal (2/4 is the same as 1/2) and which fraction is bigger.
This idea has a short entry only. For the science behind it, read the sentence above with your textbook and ask your teacher to explain the law or idea it shows, so you can describe it in your own words.
Materials
- Coloured paper strips of equal length
- A ruler and scissors
- A board
Safety
This project uses safe, everyday materials. Still, read the rules below with a parent before you start.
Never use mains electricity: power models with cells, batteries or a low-voltage adapter. Sharp and hot tools, flames and lab chemicals need an adult or your teacher beside you. Keep magnets, button cells and small parts away from young children, and wash your hands after making.
