1. Chapter One Vocabulary area composite number even number expression factor product histogram remainder multiple odd number perimeter place value prime number rectangular array scatter plot

2. Area

3. Expression A mathematical phrase that combines numbers (1,2…) and/or variables (y,z,x…) using operations (+ - x ÷).

4. Composite Number 24 15 36 21

5. Product The answer to a multiplication problem.

6. Even Numbers 12 26 42 16 100 52

7. Expressions 5 + 7 = 12 6 (3) + 5 = 23 9 x 8 = 72

8. Factors 72 = 1, 2, 3, 6, 8, 9, 12, 24, 36,72 24 = 1, 2, 3, 4, 6, 8, 12, 24 So 12 x 6= 72, 24 x 3= 72, 36 x 2 = 72 So 12 x 2 = 24, 4 x 6 = 24, 8 x 3 = 24

9. Histogram

10. Perimeter The distance around a figure on a flat surface.

11. Remainder The amount left over when the divisor does not divide into the dividend exactly.

12. Odd Number 3 25 37 105

13. Perimeter

14. Scatter Plot A graph made by plotting ordered pairs in a coordinate plane to show the correlation between two sets of data.

15. Place Value 25 Ones 248 Hundreds 2,397 Thousands 2.8 Tenths 3.85 Hundredths

16. Rectangular Array A visual model for multiplication. Example:

17. Prime Numbers 2, 3, 5, 7, 11, 13, 17, 19

18. Product 4 x 4 = 16 5 x 8 = 40

19. Prime Number A positive integer with exactly two factors, the number itself and 1.

20. Rectangular Array

21. Place Value The value of where the digit is in the number.

22. What is 5? Remainder

23. Scatter Plot

24. Area The number of square units needed to fill up a region on a flat surface

25. Composite Number A number with more than two factors

26. Even Number A whole number that is divisible by two with no remainder

27. Factor One of two numbers multiplied together to form a product. Factor X Factor=Product

28. Histogram A way to display data, much like a bar graph in that the height of the bars is proportional to the number of elements, but it displays ranges of data instead of specific measurements.

29. Multiples 5 = 5, 10 15, 20, 25, 30, 35 40… 7 = 7, 14, 21, 28, 35, 42, 49… 8 = 8, 16, 24, 32, 40 48…

30. Multiple The product of multiplying any two whole numbers (not zero).

31. Odd Number An integer that cannot be evenly divided by two.

32. Science Are everyone’s note cards made??? If not finishing making them If you are done, begin reading pages 140-143 in the science book When finished, begin working on 4.2 WB pages- due Thursday
