M1 knows about his numbers since he was 2 but I'm just making sure that he didn't missed steps, and so I'm just running through Montessori at Home-style numbers and numerals. I skipped buying sandpaper numerals but what I did was use glitter glue over Joytoy numbers puzzles to provide texture. M2 will use the same materials when he's ready. For counting we use coins, the abacus, blocks, and the small paper rolls you see above from another toy. I might ask an aunt to make us Montessori teen beads. M1 gets a little confused with numerals 6, 8, and 9, but has mastered counting 0-10+. Next up: 11-20 practice & mastery. M2 counts to 20.
