1 Going up the wall
- Open the Going up the wall spreadsheet
- Follow the instructions under the wall and write your answers in the boxes
2 Giant multiplication grid
- Start a new Google Sheets
- In A1 put an X
- In A2 to A11 put the numbers 1 to 10
- In B1 to K1 put the numbers 1 to 10
- You could format your spreadsheet – change text size, change column widths, colour column A and row 1, add grid lines
- In B2 put this formula: =A2*B1 (this does 1 X 1 and shows the answer 1)
- Copy the formula by selecting it and dragging the corner down
- This should give the 1 times table. Is it right?
- Can you work out what has gone wrong with the formulae?
- Change the formula in B2 to: =$A2*B$1
- The $ symbol means that when we copy it doesn;t change the A or the 1
- Now copy again to get the 1 times table
- Now drag across to get the other times tables
- Can you extend your mutliplication grid to be 25 x 25? Even bigger?

Conditional formatting
- Select the range of answers
- Conditional formatting:
- custon formula is
- =iseven(B2)
- choose a cell colour
- This shoud highlight even numbers
3 1-100 grid
- Set up a 1-100 grid
- Put 1 in the top corner cell A1
- Put =a1+1 next to it in cell B1
- Drag this cell to the right up to 10 (cell J1)
- Put =a1+10 underneath in cell A2
- Drag this to the right up to J2
- Then drag this row down
- Use conditional formatting to highlight different multiples
- custon formula is
- =mod(b2,2)=0 should hightlight multiples of 2
- choose a cell colour
- Screenshot the patterns and paste onto a j2e5 page
