We continue to develop, broaden, and strengthen Alexandra's number sense primarily through the physical manipulation of objects. These exercises aim to develop Alexandra's intuitive understanding of numbers, their value, how they relate to each other, and how they can be represented and used in different situations. She worked on an activity sorting and graphing by color to strengthen her one-to-one number correspondence - matching how many colors are in each category. We then worked on improving her ability to think flexibly using two sets of 5 frames before moving on to exercises with ten frames. The physical manipulation of having separate sets to add up different numbers that equal the same number helps develop thinking flexibly about numbers. We finished the exercise by connecting a ten frame to number bonds to develop Alexandra's understanding of parts of a whole. She counted by tens up to 100, requiring minimal prompts, and then added ones to the number sums counted. Alexandra also worked on an activity having her roll and build a structure using Lego and two dice and stacking the compute number correctly. This activity allowed us to incorporate concepts of proportion and equal, lesser, and greater than concepts. Alexandra enjoyed completing a connect-the dots activity, connecting numbers in sequence up to 100 and creating a picture, which strengthened not only her number sense but also her fine-motor skills using a pencil. Finally, Alexandra finished up our session playing a game of Number Bingo, with 2 cards and myself as a player - and building a marble run, aptly configuring the tubular pieces to allow the marble to follow her chosen trajectory. We enjoyed a productive and fulfilling day. Her grandpa ("papa") picked her up and she was permitted to take a popsicle home with her in the car, which made her extremely happy and her day at Batt complete!
