Reflection: Developing a Conceptual Understanding Game of Ten; More or Less? - Section 2: Whole Group Interaction

 

Adding tens and subtracting tens from any number is rather an abstract concept for many first graders to grapple with. There is a pattern in place value, though, and I have been attempting to show them this pattern and help them own it themselves. Check out the Learning the pattern of the chart video. I began teaching the concept by using base tens and ones to build numbers and show how taking away base-ten pieces and adding pieces affect the number's tens digit. From there we used a 120 chart to identify the numbers above and below the starting number and counting to identify those numbers were ten more or ten less. This lesson I attempted to show the flow of the numbers up and down each column to bring it altogether for my students.
