This week, we worked on comparing two digit numbers, solving stories, and counting groups of tens and ones. Our mathematicians worked hard to solve equations using ten sticks and ones to prove their answers.
We reviewed how to add two ones numbers together, two tens numbers together, and even a tens and ones number together. This was a snap!!
Then, we began adding a two-digit number (containing a tens number and a ones number) together with some additional ones. To complete this task, we utilized two strategies. First, our handy-dandy method of counting on:
We had to be extra careful that we counted on accurately. We made sure that we did this by always going back to double check our work. Our second strategy helped us visualize how ones can be grouped together to make a new ten – even when we’re working with larger numbers. This method is an introduction to the regrouping strategies that your child will use in second grade and beyond.
We will take our Unit 4 test next week.
