Lesson: Introducing Place Value - Tens and Ones
Objective: Student will recognize the value of two-digit numbers
Materials: T-Chart from last lesson. Base-10 blocks. Writing utensil.
- Review from last time, filling in your chart from '1' to '10'.
- Instruct child to count out 11 one units. Line up a 10-stick next to the units.
3. Point out that the 10-stick is the same as 10 one units, and substitute the 10 stick for the one units.
4. Put the 10 stick in the 'T' column, and the one unit in the 'O' column. Say, "How many tens do we have?" When child answers, "1", put a 1 in the 'T' column. Say, "How many ones do we have?" When child answers, "1", put a 1 in the 'O' column. Then recount to reinforce that you do have '11'.
5. Repeat the process, going up to 20.
Notice the better attitude in the last picture! We quit at around 13, and came back to it later. It's still a pretty advanced concept for her, I can tell, but frankly, it's good for her to be challenged. Most things come pretty quickly to Sophie, and it's good for her to not understand something, and have to press through the frustration in order to figure it out. I'm walking a fine line here between challenging her, and pushing too hard.
