    1. 1. UNIT 7 REVIEW <ul><li>Everyday Math </li></ul><ul><li>Barrington Elementary School </li></ul><ul><li>Grade 4 </li></ul>
    2. 2. Lesson 7.1- Review of Basic Fraction Concepts <ul><li>Vocabulary: numerator, denominator, whole, mixed number, improper fraction </li></ul><ul><li>Applications: </li></ul><ul><ul><li>Fractional parts of Pattern Block shapes </li></ul></ul><ul><ul><li>Fractional parts of number lines </li></ul></ul>
    3. 3. Lesson 7.2- Fractions of Sets <ul><li>Strategies: </li></ul><ul><ul><li>Base-10 blocks </li></ul></ul><ul><ul><li>Mental math </li></ul></ul><ul><li>Solve the following problems. </li></ul><ul><li>Record your answer on your white board. </li></ul><ul><ul><li>1 of 18 4 of 35 </li></ul></ul><ul><ul><li>3 5 </li></ul></ul><ul><ul><li>3 of 40 4 of 27 </li></ul></ul><ul><ul><li>4 9 </li></ul></ul>
    4. 4. Lesson 7.3-Probabilities When Outcomes Are Equally Likely <ul><li>Vocabulary: outcomes (results), probability (0-1), favorable outcome </li></ul><ul><li>Probability of an event= </li></ul><ul><li># of favorable outcomes </li></ul><ul><li># of possible outcomes </li></ul>On a 100s chart, what is the probability of dropping a cube on: - number ending in zero - even number - three digit number
    5. 5. Lesson 7.4-Pattern Block Fractions <ul><li>During this lesson you explored how the values of individual blocks change when the “whole” changes </li></ul>The whole is 1 hexagon so: 1 triangle is __________ 1 trapezoid is ________ The whole is 3 hexagons so: 2 rhombuses are ______ 4 trapezoids are _______
    6. 6. Lesson 7.5- Fraction Addition & Subtraction <ul><li>Strategies: visualize pattern block shapes, trade shapes for equivalent shapes </li></ul><ul><li>If the fractions you are + or - have the same denominator, simply add the numerators </li></ul><ul><li>If the denominators are different, trade pattern block shapes so the denominators are the same </li></ul>+ = think triangles, hexagons, so ??? - = trade in shapes so they are all the same, so ???
    7. 7. Lesson 7.5-Continued <ul><li>On your white board, record the answers to the problems below. </li></ul><ul><li>2/6 + 2/6 = </li></ul><ul><ul><li>Answer: 4/6 </li></ul></ul><ul><li>1/4 + 1/2 = </li></ul><ul><ul><li>Answer: 3/4 </li></ul></ul><ul><li>4/10 + 1/5 = </li></ul><ul><ul><li>Answer: 6/10 </li></ul></ul>
    8. 8. Lesson 7.6/7.7- Many Names for Fractions & Equivalent Fractions <ul><li>Rule for generating equivalent fractions </li></ul><ul><ul><li>Multiply the numerator and denominator by the same number </li></ul></ul><ul><ul><li>Example: 3 x 6 = 18 </li></ul></ul><ul><ul><li> 7 x 6 = 42 </li></ul></ul>On your white board, record at least two equivalent fractions for each one listed below. 1 3 8 10 Look at each pair of fractions and decide if they are equivalent. 2 6 5 20 9 24 7 28
    9. 9. Lesson 7.8-Fractions and Decimals <ul><li>Write the following fractions as decimals. </li></ul><ul><ul><li>2 57 </li></ul></ul><ul><ul><li>10 100 </li></ul></ul><ul><li>Write the following decimals as fractions. </li></ul><ul><ul><li>0.6 0.32 </li></ul></ul><ul><ul><li>19.78 </li></ul></ul>
    10. 10. Lesson 7.9-Comparing Fractions <ul><li>Like numerators: </li></ul><ul><li>As the denominator gets larger, the fraction gets smaller </li></ul><ul><li>Like Denominators: </li></ul><ul><li>The larger the numerator, the bigger the fraction is </li></ul>Put the following sets of fractions in order from smallest to largest: a) 7/12 3/12 5/12 11/12 b) 2/9 2/15 2/3 2/50 Write at least two fractions greater than 1/2.
    11. 11. Lesson 7.10- The ONE for Fractions <ul><li>Counters </li></ul><ul><li>If 6 counters is 1/3, what is the whole? </li></ul><ul><ul><li>Answer: 18 </li></ul></ul><ul><li>If 12 counters is 3/4, what is the whole? </li></ul><ul><ul><li>Answer: 16 </li></ul></ul><ul><li>If 24 counters is 6/7, what is the whole? </li></ul><ul><ul><li>Answer: 28 </li></ul></ul><ul><li>Pattern Block Shapes </li></ul><ul><li>If a trapezoid </li></ul><ul><li>is 3/4, what is the whole? </li></ul><ul><li>If two rhombuses </li></ul><ul><li> are 1/2, </li></ul><ul><li>what is the whole? </li></ul>
    12. 12. Lesson 7.11/7.12- Probability, Fractions, & Spinners and A Cube Drop Experiment <ul><li>What are the chances of landing on yellow? </li></ul><ul><ul><li>1/6 </li></ul></ul><ul><li>… on yellow, if you rolled 18 times? </li></ul><ul><ul><li>3/18 </li></ul></ul><ul><li>Landing on an even number? </li></ul><ul><ul><li>3/6 </li></ul></ul><ul><li>… on an even number, if you rolled 18 times? </li></ul><ul><ul><li>9/18 </li></ul></ul>
    13. 13. Now what? <ul><li>Visit our class blog at http://msboissebes.blogspot.com to view this slideshow online </li></ul><ul><li>Study this information on the handout </li></ul><ul><li>Ask an adult to pose similar problems for more practice </li></ul><ul><li>Stay focused, stay positive, and try your best! </li></ul>Good luck!
