Reflection: Connection to Prior Knowledge Coloring Tiles - Decimal Designs - Section 2: Concept development


I left this lesson for a guest teacher to carry out.  Upon my return I found that students had a great time and seemed to really connect with the idea of decimals relating to fractions.  Most of my students are still unsure of how to read decimals when written in isolation, but by referring to this activity and the tenths and hundredths, or their colored squares, they begin to build a deep conceptual understanding about what decimals are.

This lesson also connects to a previous lesson we did with fractions when students created a fraction Mii. You can see that lesson here. This was a great way for students and I to have the conversation about fractions and decimals being connected in that they both name parts of wholes.

You can see and hear my thoughts about preparing for this lesson for a guest teacher below.
