Week 7

alt alg subtraction: expanded and equal addends

r

Subtractionexpanded form- 135 - 24 (100+30+5) - (20+4) = 100+10+1 = 111equal addends- adding the same amount to the top number and bottom number to make one of the numbers with a zero (20) and then subtract.

a

Order of multiplication, timed tests; Expanded, lattice,
left to right, division

r

Timed tests are not very useful or helpful towards students, tracks improvement not success Order of multiplication- 2, 5, 10, 33, 9, doubles4, 6, 7, 8Expanded form- expand for place values and then multiply up then across Left to right- multiply starting with the left side similar to expanded up and across then add Lattice- draw the lattice box with diagonal cuts and write one number on the top and the second number on the right then multiply across working right to left

week 8

divisiblity rules and intro to integers

a

solving adding integers

r

Algorithm for addition- showing/writing out each integer as positives/negatives and then circling zero bank and what's left over is the answer.

week 9

build and show sub and multiplying integers

r

Start with zero bank if needed, remember positives on top and negatives on bottom same signs equal positivedifferent signs equal negatives

a

solving subtraction and multiply/divide

a

week 10

fractions intro and solving fractions (add and sub)

r

When adding whole numbers to fractions you just combine the two for your answerAdding mixed numbers with mixed numbers you add whole numbers together then work on finding the same denominator, then add

a

comparing fractions
