Kindergarten- We worked on breaking groups of 4 and 5 dots into 2 groups and writing the number bond to match. Students practiced counting to 120 while exercising. We also sang a song about shapes. They also solved 2 subtraction problems using pictures and acting. Our number talk was based on the number 8.
1st Grade- We worked on breaking groups of 4 and 5 into 2 groups, writing the number bond to match, along with writing an addition and subtraction problem for each. Students reviewed lesson 16 during a move it where they added or subtracted 10 or 1 from a number. Our number talk was based on the number 9 on a ten frame. We solved a word problem using the Bar Model Drawing Method.
2nd Grade- We practiced reading expanded notation using an activity where they revealed a mystery picture by coloring in the correct numbers.
3rd Grade- We practiced adding and subtracting multiples of 10 using a 120 chart in an activity where they revealed a mystery picture. We discussed that the ones place stays the same and the tens place changes.
4th & 5th Grades- We continued practicing the strategy of halving one factor while doubling the other factor. One class discovered that the same strategy works if you divide one number by 5 and multiply the other factor by 5 which lead us to see that it really works with any number.
