Working with Numbers 11-20 Assessment - Section 3: Summarize Data

I enjoyed seeing the growth my students experienced during this unit on numbers 11-20. I wish that I could evaluate my students individually on each standard. The assessment gave me a lot of good information, but I probably learned the most about my students understanding by observing them completing the group assessment.

Included with this reflection is a Assessment Video Clip of some of my students completing the assessment. The first student completing the assessment shows a strong understanding of place value. As he is counting the number of objects in the ten frame, he sweeps his hand over the full ten frame saying "ten". He then counts on from there. If you listen closely, you can hear him miscount. He comes up with 20. He looks at the ten frame and realizes both ten frames are not full. He knows it cannot be 20 because there is one spot open so he counts the objects again.

The second student is filling out base ten block representations of numbers. Given the number 18, the student quickly colors in the first base ten block without counting. She then carefully counts and colors in eight blocks in the second base ten block. She understands that 18 can be broken into one ten and eight ones.

The final student on the video does not show this understanding. She is counting each individual square in the ten. She does not know how to break the number down into tens and ones.

I tried to get around the room and observe each student working on these problems so I have a better understanding of this concept. I will need to continue my observations while the students are working in centers. The unit test cannot be the end of data collection and should always serve as a spring board for future instruction.

# Working with Numbers 11-20 Assessment

Lesson 17 of 17

## Objective: Students will be able to demonstrate their knowledge of numbers 11-20.

## Big Idea: The students have worked hard to build their knowledge of numbers 11-20. Now it's time to see what they have learned.

#### Individual Assessment

*10 min*

I like to do a quick individual assessment on my students to determine mastery of some of the standards. I would prefer the entire assessment be individual, but I find it difficult to find that kind of time in my schedule. The following are assessments I do individually or with a small group of students who cannot see each others' work.

Writing Numerals 0-20: For this assessment, you will need the Write Numbers 0-20 assessment sheet included with this lesson. The blank page is for the students. The students write the numbers in the boxes as they are read. (The second page of the file gives the order in which the numbers are read. Read the numbers across each row. If you note, they are in order going up and down each column for ease of recording. My students have never caught that the numbers are in order. It is important not to read the numbers in order. Some students have the numerals memorized in relationship to the numerals before and after it and do not know the numeral when asked individually.)

Counting Objects: I give the students a group of objects and I ask the students to count out 20 objects from the group. I watch to make sure they count accurately and have one to one correspondence.

Rote Counting: Students are asked to rote count to 20.

#### Group Assessment

*20 min*

For this assessment, you will need a copy of the Assessment-Working With Numbers 11-20 included as a PDF. After I compete the individual assessments, I use this group assessment. Although I prefer to use individual assessments whenever possible, I do not have the assistance in my classroom this year to assess every child individually for each standard. This group assessment makes it more manageable to collect data on my students

I have the students take their "testing positions" in the classroom. They each have an assigned assessment spot that keeps them from looking at their neighbor's paper. I read each question aloud for the students and circulate around the room. I take notes on which students may need to have a separate assessment on certain standards based on their responses. Upon completion of the test, the students turn in their tests.

#### Summarize Data

*5 min*

After the students have completed the individual and group assessments, I complete the Assessment Summary Sheet for each student. I record the results of the individual assessments and the group assessments in the corresponding sections on the sheet. This sheet allows me to see what students need more work in mastering concepts and it also gives me a good foundation for discussion with parents in regards to their child's progress in math.
