Percentages

40% of 80

10% of 80=8

multiply both sidew by 4

Week 12: PEMDAS/GEMDAS

Repeated subtraction goes with long division*

*line up your whole numbers not your decimals*

Divisibility Rules: (2,3, 4,6,8,9,10)

Same Rule: (2,3,6) (3,9) (4,8) (5,10)

algorithms for division: “Reverse C”

Division

24/9 divided by 10/6= keep.change.flip

6 divided by 1/2= How many groups of a 1/2 go into 6

10/2 = breaking up 10 into 2 groups

Multiplying simplifying fractions

FINAL WEEK: Aolve using AREA MODEL

Let X=10 Example: 5(2x+4) (distributing)

*multiply

*expanded form

Convert from bases to base 10 /draw diagrams use algorithms

Order of operrations

Show using a diagram: (+/-/x)

GCF/LCM using fractions

missing pieces/smaller or larger stating reasons

Show X & Y using tiles

adding/subtracting

Keep. Change. Change.

Main topic
