Math Workshop- this teacher explains exactly how she conducts her guided math lessons in her third grade classroom. (extremely informative post that includes a FREEBIE!) and now she also has detailed lesson plans!
I would use this as an anchor chart to teach students about rounding decimals. I liked this because it rhymed and would help student s to remember. This aligns with the grade TEKS because it teaches students to round to tenths or hundredths.
