Place Value Posters

The students used Pixie 2 to create place value posters in the computer lab. They first learned how to create lines to divide the paper in fourths. We have been working on the skill of "click, hold, and drag." They then chose a larger number to model. They then learned to use text boxes to type in various ways to model the number. For example, they typed the number in standard form, expanded notation, and written form. They also drew the tens and ones as a pictorial model. Once they were printed, the students worked in partners to determine which number was the greatest and/or least. They then worked together to type the comparison sentence.

Place Value Comparisons

The students were each given four number cards to model in a drawing as tens and ones on a foldable. They then wrote comparison sentences to determine which number was the greatest and which was the least.

Building Larger Numbers

The students rotated through stations in small groups to build larger numbers with pop cube tens and bean ones. At each station they had a number card telling them what number to build. They then recorded their number on the top flap of a foldable and modeled the number as a picture under the flap. When possible, I like having the students work in small groups to allow them to teach each other and give/receive feedback.

Depicting Larger Numbers

In a training with one of our district math strategists, we learned a technique to get students to show what they know. Each group has a different pen or marker color and completes one portion, task, or question at a given station. They then rotate to the next station and do the same. They either add to what the other group has done or come up with a different answer. Using this idea, I created Place Value Depictions to 120. These worksheets allow students to depict numbers in pictorial models (sticks and dots for tens and ones), on a tens/ones chart, in expanded form, and in written form. I set up stations around the room with one of these worksheets at each. The students rotated to each station until all the ways to depict the numbers were completed. I loved it because the students could not always rely on completing the portion that came the easiest to them - someone else may have already done that portion. The kids loved it because they got to work together and it was like a puzzle to them. I plan to continue having the kids work on these in math tubbing. Once we have a complete set, I will bind them as a class book for them read as review. You can download the file here.

Pumpkin Patch Place Value

Each student was given a bag of candy pumpkins to count during a Place Value lesson. They used a ten rod sheet to help sort the candy in rows of tens. We discussed that it is quicker to count by tens than by ones because ten is a larger number. After making their pumpkin patch with the candy, they recreated it on the ten rod sheet by thumb printing pumpkins. They then completed a recording sheet to identify how many tens and ones were in their pumpkin patch as well as the expanded notation. Their work was bound into a class book to use during Math Tubbing. The templates can be downloaded from my Teachers Pay Teachers store.

Place Value Initials

To practice building larger numbers, the students used printable base ten blocks to build the first letter of their name. They then counted how much their name was worth. The pages were later bound together as a class book so the students can practice counting the larger numbers during Math Tubbing. You can download the template here.

Place Value Depictions to 120 Download

Fellow teachers, I just created a new place value download, Place Value Depiction to 120, for my Teachers Pay Teachers store. These printable posters allow students to depict numbers through pictorial models, expanded notation, written form, and on a tens/ones chart. Students can compare numbers using the various number depictions. The posters can be completed individually or in small groups to reinforce place value skills. The posters can be bound together as a book once completed to use as review. The posters can also be used to assess students' understanding of the place value concept.

Comparing Larger Numbers

When possible, I think students should be able to work together in small groups. It not only adds to their engagement and motivation, it gives them an opportunity to explain how they did their work and why they think something. Recently the students worked in small groups to build various larger numbers with Base Ten Blocks. As they built, they checked one another's work. Once all group members had built the correct number, they drew a model of the number with sticks (tens) and dots (ones). They again checked one another's work and then proceeded to the next part. They identified how many tens and ones, the expanded notation, and then ordereed the numbers from least to greatest and/or greatest to least.

Modeling Larger Numbers

During our last unit of Place Value, the students worked in groups to create three flap foldables to record various ways to write numbers. The students drew out number cards and recorded the number on the top flap. Under the flap they drew the number as sticks (tens) and dots (ones), identified the number of tens and ones, the expanded notation, and the written form. As they worked, they discussed which number was the greatest or least and justified their answer using the number of tens and ones each number had. They then compared their numbers with other groups.

Modeling Larger Numbers

In math we are working on modeling, ordering, and comparing numbers to 99. In this lesson the students worked in partners to build larger numbers with Base Ten Blocks. They then checked on another's work. After both partners agreed the models were correct, they represented their numbers on paper by drawing sticks (tens) and dots (ones). They then identified in writing the number of tens and ones, the expanded form, the standard form, and the written form of the numbers. They then again worked with their partners to check the work.  After checking, they discussed which number was the greatest and which was the least. They had to justify their thinking by explaining how many tens and ones were in their numbers. The partners then switched numbers with another set of partners and repeated the process.

Place Value Race

To help review place value concepts, we have been having short place value relay races. The class is divided into three groups and they sit in rows. I write three larger two-digit numbers on the board and the students compete to see who can describe the number in picture form (sticks and dots), standard notation, and expanded form. If they need help, they can ask their teammates. The team who finishes first correctly gets three points, second place gets two points, and third place gets one point.

Base Ten Flashcards to 100

Fellow teachers, I created an extensive set of Base Ten Flashcards to 100. The set includes five different ways to represent the numbers: pictorial representation with Base Ten Blocks, numerical form, number of Tens/Ones, expanded notation, and word form. Ideas for using this resource include but not limited to:
  • Play “Around the World” to review
  • Create a Tree Map to show various ways to represent numbers
  • Play “Concentration” to match various ways to represent numbers
  • Build numbers using manipulatives
  • Order cards from greatest to least, least to greatest
You can download the flashcards at my TPT store.

Place Value Initials

The students practiced building larger numbers using paper Base Ten Blocks by creating the initial of their first name. After building their initial, they recorded how many tens and ones their letter contained and then wrote the expanded notation.

Place Value Pumpkin Patch

The students created Place Value Pumpkin Patches to help them count larger numbers by tens and ones. They first built various numbers using candy pumpkins. They then took a gallery walk to count one anothers' pumpkins. They then recreated the pumpkin patch number on paper ten rods by painting with their thumbprint. The students then wrote how many rows of ten and how many ones were in their pumpkin patch and how much those numbers were worth in expanded notation. Fellow teachers, you can download the templates for FREE on my TPT store.
