Students love finding the errors in Puzzled Penguin's work and sharing their thinking with their math partners. The 100s charts are a hit, students are filling in blank 100s charts using expanded notation, tens and ones and reading the numerical words and finding the correct location on the empty charts. Mental math has worked its way into centers this week too! Students spin and read the number to their partner and ask them to add or subtract 10 in their head.
