Place Value Round Up--Representing Numbers 11-20 with Base Ten Blocks and Ten Frames - Section 2: Independent Practice and Informal Assessment

The students LOVED this activity! They were helping each other find the animals hidden around the room. It was fun to see the excitement and the teamwork they demonstrated. I love these types of activities for reinforcing skills. Because of the design of the activity, the students do not even realize that they are practicing an important skill.

The activity also gave me the opportunity to observe the students as they worked. It was fun to see how many of the students really understand the concept of place value by observing whether they said "ten" when counting the rod or the complete ten frame.

When the lesson was all done, one of my students actually said, "Mrs. Baumann, we forgot to do math today!" What a fun lesson!

This lesson is intended to be a another fun review of place value for the students. The students move about, looking for animals and then representing the animals numbers with base ten blocks or ten frames. For this portion of the lesson, I use my SMARTBoard. If you have a SMARTBoard, the file can easily be downloaded and opened. If you have a different type of interactive whiteboard, you can still use this lesson by opening the file in Smart Notebook Express. There is also a PDF of the slides so you can recreate this part of the lesson.

I gather my students in front of the Smartboard. I have cards with each student's name on. These cards are used for selecting who will come up to the SMARTBoard.

I open the first slide (SMARTBoard Slide 1) with the lesson objective written in "student friendly" terms. There is a content objective and a language objective to help focus on vocabulary expansion for my English Learners (ELs) to be congruent with SIOP instructional techniques. I read these objectives aloud for my students.

**Content Objective **I can represent numbers with base ten blocks and ten frames.

**I can tell a friend how to represent a number with base ten blocks and ten frames.**

We then continue with the rest of the slides.

**Slide 2:** *Let's go on a round up and find some numbers! Do you know what a "round up" is? That's right. Cowboys go on a "round up" to gather their cattle. We are going to round up all kinds of farm animals today and practice our place value.*

**Slide 3:** * Fill in the blocks. You can make an X in each block to show it is filled in.* I invite a student up to the board to fill in the place value blocks. The class checks the work when she is done by counting the number of blocks filled in to see if the number is the same.

**Slides 4-5:** We continue as in Slide 4.

**Slide 6:** *Now let try a ten frame.* I invite a student up to move the red circles over to fill in the ten frame to match the number. Again we count as a class, checking to see if the number of spaces filled in is the same as the what the animal is saying.

**Slide 7-8:** Continue as in slide 6.

*Excellent job! Now let's go back to our seats and round up some animals and numbers for some more practice!*

For this part of the lesson, you will need the Place Value Round Up activity set included as a PDF with this lesson. I print the file on a color printer. I adhere the cover page to a 9x12 envelope to store the pieces in. I laminate all items for durability. After the cards are cut apart, tape the animals around your room. Place some in obvious places and make others a little harder to find. You will also need copies of the recording sheet included in the file for each student in your class.

I say to the students, *okay boys and girls. It is time to have a round up. There are several animals hiding in our classroom. It is your job to find all of them. I want you to find all the animals. We will not disturb our animals, but I need a way to know that you have found them all. I want you to read the number that is on animals' card and then fill out the base ten blocks or ten frame next to the animals picture with the same number. When you are all done, bring me your sheet and I will check your answers* (I make a "key to assist in checking the answers).

I send the students on the round up. I circulate around the room and observe their work, assisting as needed. When the students are done, I check their work against the answer key I created. If they have a mistake, we find the animal together and they represent it again with my assistance. The students then put their papers in their mailbox.
