Monday - Math Improper fractions and mixed numbers CW / HW: WB pg. 58 (1-11)
Mountain Math – Due Friday A A B A C
Pattern Blocks How many hexagons fit into a hexagon? 1 hex = 1 How many trapezoids fit into a hexagon? 1 trap = 1/2 How many parallelograms fit? 1 par = 1/3 How many triangles fit? 1 tri = 1/6
Make some changes! • Trade in the following for as few pieces as possible.
1 = 4 2 9/2 9 trapezoids = 9/2
The MATH! 4 This becomes the DENOMINATOR! ) 9 2 2 -8 Instead of becoming a remainder, this is the NUMERATOR! 1
151 = 2 6 2 Your turn! 15/6 Trade the triangles in so you end up with as few pieces as possible! Simplest Form
The MATH! SIMPLIFY 2 ) 15 6 6 -12 3
Go the other way! This time, trade your pieces so that you end up with as MANY as possible!
The MATH! • When you change a mixed number into an improper fraction, you have to be… b-B-add...
2 3 6 20 6 How to be b-B-add: b…bottom times B…BIG, then Add…the numerator 6 x 3 = 18 + 2 = 20 Keep the original numerator
Try it again! Trade your pieces so that you end up with as MANY as possible!
Class work…or home work • WB pg. 58 (1-11) • You can use the pattern blocks while you are in class.
