During these lessons, students practice grouping ones into sets of 10s and sets of 10s into 100s. Children bundle their groups to make counting and adding larger numbers easier. They also identify the value of digits and learn how to write numbers in expanded notation. Finally, they will learn skills that will help them compare larger numbers.
Let’s Bundle! Students use coffee stirrers to create bundles of 10 and bundles of 100. This is an introductory, hands- on lesson to get students thinking about grouping numbers. (We searched Amazon and found stirrers available for the lowest price below.)
Show Me! Use these large, printable digit cards to get students up and moving during math. Tell students a number and they stand in a line to create it. Print more than one of each digit to make it more challenging. Once students are in their order, have them tell you what place they are standing in. As an extension, have students tell you the value of their digit.
Roll the Dice! Students roll three dice and complete the printable activity. Students create the number, identify the digit in each spot and tell the value of each.
Counting 1s and 10s This works well as a whole class activity or as a station. Before students complete this activity, you will want to have a mini-lesson on tens and ones in a number. Students also need experience with identifying the value of digits in a number. For example, students need to know that the 7 in the number 74 is worth 70. To prepare for the activity, place sets of 1s and 10s in snack size baggies (you will need 8 or 16 sets depending on the amount of practice you think your students need.) Number each bag with a Sharpie. Students open the bag and practice counting how many they have. They fill in the counting 1s and 10s paper.
Counting 1s, 10s and 100s (Like the above activity but with 100s – almost finished!)
Make the Number A file folder game where students practice making the number using bundles. Make the Number 1 Make the Number 2 Make the Number 3 (blank so the the teacher can use a Vis-a-Vis marker to write their own numbers.)
Place Value Chips Print, laminate and use a 1 inch hole punch to create place value chips. Place them in a bucket and students take a small handful without looking. The students then record how many of each they have and write the number altogether. Printable Recording Form with 100s, 10s and 1s Printable Recording Form with 1,000s, 100s, 10s and 1s We’ve had requests for the recording form with words! Here it is: Recording Form – Words
If you don’t have 1st, 10s and 100s units, you will want to get some for your classroom. Below are two sets we like (We like that the second set is magnetic – this would be great for modeling with a small group or whole class. You can stick them on the board so all students can see.) We also suggest Unifix cubes because students can put them together and take them apart. The Common Core Standards refer to bundling in second grade. In our classrooms, we are using bundles of coffee stirrers. They are inexpensive and look like the clip art that will be used on PARCC test in the future. Plus, students get hands on practice with putting together and taking apart bundles.
