alt alg subtraction: expanded and equal addends
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.
aOrder of multiplication, timed tests; Expanded, lattice,
left to right, division
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
divisiblity rules and intro to integers
solving adding integers
Algorithm for addition- showing/writing out each integer as positives/negatives and then circling zero bank and what's left over is the answer.
abuild and show sub and multiplying integers
Start with zero bank if needed, remember positives on top and negatives on bottom same signs equal positivedifferent signs equal negatives
