Today's lesson was on counting, reading, and writing 13, 14, and 15, focusing on 14. Libby used base ten cubes to model 14 with one tens stick and 4 ones and colored in pictures of base ten blocks, tens frames, and objects to model 14. Then, she counted groups of 13, 14, or 15 objects and wrote the amounts. Finally, Libby solved subtraction problems by taking away 1 within 10 and she counted to 100 using base ten blocks and her hundreds chart.
