3 -5 SUMS Training: Model Drawing

Branching Method: 64 + 13 60 + 4 + 3 + 10 4+3 60 + 10 RE Te MIND the ns go ER: ou on tsi de ! Answer: 4+3=7 60 + 10 = 70 7 + 70 = 77

Branching Method Cont. 53 - 45 53 - 53 – 45 = 45 40 +13 - 5 + 40 Answer: 13 - 5 13 – 5 = 8 40 – 40 = 0 40 - 40 8+0=8 ?

Branching with Regrouping R: E ND on I M ! RE ns go side Te out the 64 + 18 64 Answer: 4+ 8 = 12 60 + 10 = 70 + 18 60 + 4 + 8+10 12 + 70 = 82 4+8 60 + 10

Left – to – Right Method 132 + 245 (100 + 30 + 2) + (200 + 40 + 5)= Break apart the numbers (100 + 200) + (30 + 40) + (2 + 5) Answer : 300 + 7 = 377

Lattice Multiplication or Area Model: 2 x 12 Step 1: Draw your box Step 2: Draw your diagonals to show place value Step 3: Label the numbers you are multiplying Step 4: Multiply Step 5: Add the diagonals 1 0 0 2 2 2 0 4 4 Answer: 24 2

Lattice Multiplication Cont. 4 2 6 2 3 1 45 X 58 5 0 2 2 5 5 4 8 0 0 Answer: 2, 610

Multiplying using the Left – to – Right Method 461 X 7 (400 x 7) + (60 x 7) + (1 x 7) = (2, 800 + 420 + 7) = 3, 227

FOIL Method 63 x 46 F = First O = Outer I = Inner L = Last 63 x 46 (60 + 3) x ( 40 + 6) F - 60 x 40 = 2, 400 O - 60 x 6 = 360 I - 3 x 40 = 120 L- 3 x 6= 18 + Answer: 2, 898

Partial Quotient/Division 4 345 200 50 145 120 30 25 24 + 6 1 86 R 1 345 ÷ 4 Questions to Ask: How many 4’s are in 300? How many 4’s are in 145? How many 4’s are in 25?
