About the Mathematics in Unit 8
Our class is starting a new unit in mathematics called Ten Frames and Teen Numbers. The focus of this unit is on understanding and solving addition and subtraction problems in a variety of contexts (i.e., games, activities, story problems), recording and representing solutions on paper, making sense of the teen numbers (10–19) as a group of ten ones and some number of leftovers, and counting by 1s and 10s to 100.
Students solve story problems and discuss and compare their solution strategies with classmates. They practice counting by 10s as they count the number of fingers on 10 students. They play games where the cards that indicate how far to move (or how many to take) have “facts” on them so that students develop fluency adding and subtracting within 5 (e.g., 3 + 2 and 4 - 1). They also work on a variety of activities that involve number combinations focusing specifically on combinations that make ten and on the teen numbers.
