Today, we worked on counting, reading, and writing the number 18. Libby used base ten cubes to model 18 with one tens stick and 8 ones and colored in pictures of base ten blocks, tens frames, and objects to model 18. She also traced 14 through 18 in number and word form for review. Then, we used flashcards to practice adding to ten to help quickly recognize adding a single digit to 10. Libby finished with plus and minus 1 fast facts.
