The 120’s chart is a great tool for practicing place value, expanded form, and addition facts. Additionally, when students place numbers on the 120’s chart, they are learning to notice patterns between numbers. As students become faster in completing the chart they ‘level-up’ to other card sets.
6 Levels of Cards Included:
Level 1: Number Cards
Level 2: Place Value Pieces
Level 3: Tens & Ones
Level 4: Expanded Form
Level 5: Subtraction Facts (from a ten...50-4)
Level 6: Addition Fact (from "9" to encourage making a 10...39+7)
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). Then, students use the expanded form of each number to place it on the chart (30 + 8). I use Set 5 later in the year when we work on subtraction and Set 6 when we need practice Making 10 to Add.
To keep the cards organized and easy to sort, I copy them on colored cardstock, each set in a plastic baggies, magnet-ed to the back of a filing cabinet where our 120s chart hangs. Students know which baggies to grab and love to beat their fastest time!
