Activity: Cross-Number Puzzle
Here’s a cross-number puzzle to give you some more practice using the calculator. It’s like a crossword puzzle, only with numbers instead of words. Draw the puzzle in your math notebook and then use the calculator to solve it. Do a few of the calculations in your head or on notebook paper, if you feel up to it. That makes great practice.
The calculator can be accessed on the left-hand side bar under Toolkit.
One great thing about cross-number puzzles is that hints are built into the puzzle. Most digits have to be correct in both directions, across and down.
- You can use the buttons on the calculator or the keys on your keyboard to enter numbers and mathematical signs.
- Remember to clear each calculation before you begin the next using C.
- Watch the screen as you enter the calculation to make sure that it is correct.
- If a calculation or answer is very long, you may have to look for the complete answer in the white window, underneath the cropped number that shows in the black window.
