Formemos números con 10 y algunos más (parte 2)
In previous lessons, students saw numbers 11–19 as ten ones and some more ones as they counted, composed, and represented these numbers. The purpose of this lesson is for students to use the understanding that a full 10-frame contains 10 ones to compose numbers 11–19. Using a 10-frame encourages students to count on from 10. While this lesson highlights counting on as a strategy, students need significant practice working with 10-frames before they are able to count on to determine the total with understanding. Students can complete the activities by counting all. Counting on to determine the total is not an expectation in kindergarten.
Activity 2: Formemos cada número
- Compose and decompose numbers 11–19 using 10 ones and some more ones.
- Mostremos números con tableros de 10 y puntos o fichas.
