A spreadsheet is a grid that calculates. Type numbers into its cells, add a formula, and the answer appears — and updates by itself whenever a number changes. Year 5 coders learn to read cell names and write simple formulas.
Apa yang akan dipelajari anak anda
- Name a cell by its column letter and row number
- Know that a formula starts with an equals sign
- Use cell names in a formula, such as =A1+A2
- Use SUM, AVERAGE and MAX on a range, and sort and filter data
Formulas point at cells
The formula =A1+A2 doesn’t add two fixed numbers — it adds whatever is in those two cells. Change A1 and the answer changes with it. A range such as A1:A5 means “all the cells from A1 to A5”, so =SUM(A1:A5) adds five cells in one go.
