Background For Teachers:
This lesson uses math journals, assuming that each student has been
using one throughout the year. A math journal is a great way for students
to record their thoughts about math lessons, new discoveries, example
problems, and math definitions. Any type of notebook works well. If
you do not use math journals, students can write the results on a piece of

Irwin, K.C. (2001). Using Everyday Knowledge of Decimals to Enhance Understanding. Journal for Research in Mathematics Education, 32(4), 399-420.
“Half the pairs worked on problems presented in familiar contexts and half worked on problems presented without context.” This article presents results of an investigation that showed students who were presented decimal problems in a familiar context succeeded more often than students who were given no context.

“Recent research has convincingly documented elementary school childrens’ tendency to neglect real-world knowledge and realistic considerations during mathematical modeling …” This article suggests that using real-world modeling can help students have a better disposition toward mathematical concepts.
