Previously Published Data

1.) Students select a number 3-20, and build several towers, using the indicated number of linker cubes, with different color combinations. They write the equation for each tower. Students who picked the same number compare their work. 

2.) Students work in a small group. One student pulls a card from a deck numbered 1-10 and shows it to the group. The others write down as many number combinations as possible, whose sum is indicated on the card. Students take turns drawing a card.



Previously Published Data

Assessment will be done on an individual basis by the teacher/ helper 1.) Students select a card numbered 3-10. They write down all the different number expressions that equal their chosen number, such as if they picked 4, they would write 4 + 0, 1 + 3, 2 + 2. 2.) Students build three different cube towers, using various colors, to represent the number 7. 3.) Students explain how they would sort 34 cubes using cups of 10. Students perform this task, draw a picture of their work and label it.
