Наслов Addition strategies within 10 (or 20)
Опис This lesson emphasizes explicit representations of addition expressions and solutions. The sim allows for students to solve using Ten Frames, free objects, or a linear representation that can function like a number line. These tools can support various direct modeling and counting strategies. This lesson focuses on the use of the Lab screen specifically because it does not provide immediate feedback regarding the total number of objects. (If feedback is desired, a class could use the Ten screen instead.)
