Overview:
In this activity, students practice determining different ways to make 10. They work together as partners and roll dice to determine the numbers they work with. They have to evaluate their numbers rolled to find a way to make a total of 10. They color in their bars to represent the numbers they rolled. A number sentence is composed and then they move on to the next roll. Once the activity is complete, a whole group discussion takes place and all the combinations that the students found are listed on the board.

Alabama Course of Study Alignments and/or Professional Development Standard Alignments:
MA2015 (1)  1. Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (See Appendix A, Table 1.) [1OA1]   MA2015 (1)  4. Understand subtraction as an unknownaddend problem. [1OA4] Example: Subtract 10  8 by finding the number that makes 10 when added to 8.   MA2015 (1)  5. Relate counting to addition and subtraction (e.g., by counting on 2 to add 2). [1OA5]   MA2015 (1)  6. Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13  4 = 13  3  1 = 10  1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12  8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
