If you use interactive math notebooks or journals, or if you want a fun and engaging alternative to worksheets, this is a great way to start!
With my students, they cut out the title and glue to their journal, and then cut out the squares with the problems and tabs. They glue the tabs (seperated by a thin line so they don't cut it off), and fold them back to create a flap when it is glued down. Then they write the number represented by base ten blocks underneath the flap.
Once the page is complete, they have a great resource for partner quizzing or self-checking. This would work fine on regular paper without the notebook, also!
