Students will build and deconstruct numbers to 10 using manipulatives, explaining their reasoning.
Use 5 frames and 10 frames in math journals to record their reasoning, e.g., show a 5 frame with 4 dots and have the sentence frame: I know this is __ because __
. with space for them to draw or write their explanation.
Use rekenreks to have students show how to build numbers to 10.
