Today, we began the lesson on counting, reading, and writing 16 and 17 with a focus on the number 16. Libby used base ten cubes to model 16 with one tens stick and 6 ones and colored in pictures of base ten blocks, tens frames, and objects to model 16. Then, she worked on mixed facts on adding and subtracting 1. She was encouraged to focus on the operation sign and use her number line for help. Finally, we counted to 100 by ones and tens using the hundreds chart.
