This PowerPoint will guide your students through an activity in which they will learn about place value. Instead of just memorizing place values, this activity is designed to allow students to use knowledge of place values to create numbers. The switch to Common Core requires that students have a deeper understanding of content. I tell my students that math is like play dough! You can mold and create new things using numbers! In order for students to critically and creatively think about math problems, they must understand that numbers are simply symbols that represent groups. Where the symbols (1, 2, 3, 4...) are placed tells us what is in each groups (ones, tens, tenths....). I have my students write a number on their personal white boards. Then they use their hundreds squares to create that number. The template for the hundreds squares can be found on the last slide of the PowerPoint. The students can cut some of the squares into tenths, hundredths, and even thousandths (even though they are so small you can barely see them...). During the activity, I ask the students if a "9" in the thousandths place is more or less than a "1" in the tenths place. I was ecstatic to see some of my students that have struggled so greatly in math have an "Ah Hah!" moment during this activity. I hope you experience the same!
