The 120’s chart is also a great tool for practicing number sense, place value, and expanded form. When students place numbers on the 120’s chart, they are learning to notice patterns on the 120s chart. Throughout the first semester, this is a continuous center in our math rotations. As students become faster in completing the chart (many times it initially takes 25-30 minutes to complete the chart, while only 10-12 minutes when they have mastered the patterns/skill). Students ‘level-up’ as they work with the chart.
Initially I only use the number cards (1-120) for all 3 of my math groups. Students pull a number and then, place it in its home. Many students will individually count each square on the 120s chart until they find the desired home. Eventually, students will discover ‘tricks’ for finding the number’s home – counting by tens, noticing the number’s relationship to other numbers in the 120s chart, etc.
After students are successful using the number cards, I introduce the Place Value cards. These place value cards are perfect for practice counting tens and ones. Next, I introduce the tens/ones cards for the numbers (1 ten 8 ones). Finally, students use the expanded form of each number to place it on the chart (30 + 8).
We’re also using Place Value Path by The Measured Mama in centers. She has already included 3 differentiated board games, so it’s perfect for all my math groups. I copy the boards on different colors of card stock (yellow, blue, green) and they are ready to go!

Hello Catherine, I was doing some research the other day and came across your site, wonderful by the way. I realize that you no longer teach 5th grade at this time; however, I would like to know how you used socrative to set up your center work. I purchase many of the centers you used in your literacy centers for big kids post and want to know how i can hold my students accountable for their center work. Any information given would be great thanks
Hi, Thanks for all of the ideas. I was moved from K to 1st this year and sometimes its like my 1st year all over a gain (15 years later). We are just finishing Numbers and Operations and will be starting Place Value on Monday. Do you do mainly whole group or small groups or both for math? Thanks for sharing. Karen

Where did you get your spinners from? I love that they are clear!!
Your hands on approach to teaching place value in 1st grade is truly inspiring. It is wonderful to see how you engage students with various manipulatives and creative activities making the learning process both enjoyable and effective.
