MTE 280 Mind Map
The content covers various mathematical principles and methods such as solving equations using the area model, distributing factors, and converting between different numerical bases like base nine, seven, and five to base ten.

Drawing: fractions/showing adding fractions *Smaller the number= bigger the piece *Bigger the number= smaller the piece Using colors Anchor fraction SUBTRACTING INTEGERS Add using alternative algorithms

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 Comparing fractions Providing Reasons Less than Greater than Using colors/fractions PRIME FACTORS COMPOSITE #'S (3 FACTORS OR MORE) mULTIPLYING 1 BY ITSELF (ONLY 2 FACTORS) GCF/LCM Using small/big exponents Factor Tree Upside down division Upwards Division Lesson: "Integers" yellow= positive
Red= negative subtracting with
or without Parenthesis Unit #2 Warm Up
Add using any

any method Base nine Base seven Base five 4 step problem solving process Covert from bases to
base 10 Drawing Diagrams Diagrams + Algorithm BUZZ Memory Counting Multiples of a number FLU Flats, Lengths, Units 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 Denominator/numerator Numerator: # of pieces that I have Denominator: tells size of pieces Multiplication/division rules for integers Signs are different.. ANSWER IS NEGATIVE Signs are same... answer is POSITIVE Integers including (x and /) Show using integers drawings left to right expanded form Friendly numbers scratch method base five scratch base seven if in base 10 count up to 10 then scratch Area Model lattice subtracting adding multiplication Converting bases Using Algorithm Using Diagrams Numbers and Operations in
