Across
- 3. fractions that have the same denominator
- 5. the answer to a subtraction problem
- 6. the answer to division
- 8. the smallest common denominator (like the least common multiple)
- 11. a positive or negative whole number (no fractions or decimals)
- 12. the bottom number of a fraction
- 13. opposite of positive; the part of a number line left of zero
- 14. technique that allows subtraction problems to be changed to addition; the first number stays the same; the minus sign changes to an addition sign; the second number changes to its opposite (positive/negative)
- 18. – The distance a number is from zero (positive version of a number)
- 19. fractions with different denominators
- 20. the top number of a fraction
- 21. dividing both the numerator (top) and denominator (bottom) of a fraction by a common factor until there are no common factors that will divide into both

Down
- 1. opposite of negative; the part of a number line right of zero
- 2. graphic representation of numbers with positive numbers to the right (or above) zero and negative number to the left (or below) zero
- 4. a fraction where the numerator (top) is larger than the denominator (bottom number)
- 7. a number representing part of a whole; looks like a number on top of another number
- 9. the answer to multiplication
- 10. technique used when dividing fractions. Keep the first fraction the same; change the division symbol to multiplication; flip the second fraction (use the reciprocal)
- 15. tools used to make sense of adding and subtracting integers; often using 1’s or +’s or Yellow circles for positives and O’s, –‘s or Red circles for negatives
- 16. a number with no fractional or decimal parts
