Bear worked on static adding (no regrouping) of 4 digit numbers this week with the Montessori golden materials. This is know as “Unlimited Bead Exercises” in Montessori lingo. She builds the two numbers first (a game called Formation of Numerals) and then adds them together. I had to modify the presentation to make it work better for us as I only have one set of number cards. I write the questions for her in a notebook and she writes the answer into the notebook. This allows me to keep a record of the work she has done.
She worked on sensorial extensions using the brown stair and pink tower. She keeps coming back to this one ever since she got to do it in school with a friend.
We also used a grid game from prekinders but modified it so she could practice her addition facts – she rolls the die twice and find the sum to put on the grid.
