Jim: "Because I added, 3 with 7, that makes ten, then added 3 more, and that's 13", "grouped it down-(counting down)", "flipped them over (counting down again)", 13 take away 3 would be 10 and 10 take away 1 is 9
Lauren: 7+7=14, so 7+6=13, counts down in groups of numbers
Elizabeth: 7+7=14, so 7+6=13, knows six is one less than 7, so that makes the answer 13 instead of 14, grouping-5+5=10, 10+2=12

Students have learned to add and subtract by grouping. Students have also had more practice with adding and subtracting larger numbers. Students know how to subtract by counting down. Students have a better concepts of number relationships. Students rely less on using fingers or objects to add and subtract and focus more on doing the math mentally and reasoning out the problems.
Were there any specific number strategies that you saw students using consistently?
ReplyDeleteMost of the children started to use grouping as one of their main means of solving the problems.
