Students in Kindergarten model the action of joining and separating, solve word problems using objects and drawings to find sums up to 10 and difference up to 10, and explain the strategies they use to solve problems within 10. Strategies include using spoken words, concrete and pictorial models, and number sentences.
In First Grade
In first grade, students will generate and solve problems within 20 using basic fact strategies, concrete and pictorial models and number sentences. Students will also determine the unknown whole number in an addition or subtraction equation when the unknown can be any one of the three or four terms in a number sentence.
