CH 6, 7, & 8 Test Review

You should be able to:

1. Provide a pictorial representation of fractions, whether using a discrete whole or a continuous whole.
2. Write a decimal number as a fraction in the form: i.e 2.25 = 225/100 = 9/4, or 2.2525252525... = 223/99
3. Demonstrate understanding of decimal numbers by finding numbers that would be between consecutive decimal numbers. i.e. what decimal numbers are between 0.2 and 0.3
4. Use approximation to find an estimate of the answer when doing addition, subtraction, multiplication or division involving mixed numbers.
5. Find a fraction between fractions with unlike denominators without converting to decimal numbers or using common denominators. This means understanding how “neighbor numbers” work.
6. Illustrate multiplication and division of fractions
7. Explain additive and multiplicative comparison and be able to write word problems that illustrate this knowledge
8. Illustrate multiplicative relationships (similar to the chocolate bar activity in ch.8) and use that knowledge to solve problems
