Overview:

This second-grade engagement activity uses Quick Images in a Number Talk format to begin to build a conceptual understanding of compensation, which is the underlying concept behind the "Make it Friendly" addition strategy.

This activity was created as a result of the ALEX Resource Development Summit.

  Associated Standards and Objectives  
Content Standard(s):
Mathematics
MA2015 (2016)
Grade: 2
9 ) Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction. [2-NBT5]


Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.2.9- Identify the meaning of the + sign (add, plus, put together) and the - sign (subtract, take away, take from) and the = sign (equal, the same as); compose and decompose numbers up to 30 using objects, pictures, drawings, or numbers.


Learning Objectives:

The student will use an efficient strategy to add within 100.

The student will orally explain their strategy.

  Strategies, Preparations and Variations  
Phase:
Before/Engage
Activity:

  1. The teacher will open the Google Slides Presentation, Make it Friendly.
  2. The students will read the learning targets (Slide 2).
  3. The teacher will introduce the common vocabulary (efficient, strategy) to be used in the lesson (Slides 3 and 4).

  4. The students will be participating in a Number Talk. The teacher introduces or reviews the procedures for a Number Talk. (Slide 6)

  5. After introducing or reviewing the procedures, the teacher will begin the Number Talk using Quick Images to help students think about making a ten, which is a common method for making numbers friendly to combine. The teacher will flash the tens frame for 3 seconds and then quickly click on the next slide. The students should not have enough time to count the dots. The goal is for them to mentally move the dots from one ten frames to the other to complete a ten (Slide 7).

  6. When the students orally explain how they determined the total, the teacher will record their thinking using numbers. For example, if a student says, “I took one of the dots on the left tens frame and moved it to the tens frame on the right to make a ten. I knew 10 plus one is eleven.” The teacher would record 9 + 2 = ?,  2-1 = 1, 9+1 = 10, 10 + 1 = 11. This can be written vertically or horizontally. Also, if the teacher is projecting on a whiteboard, he or she may want to draw arrows to show how students moved the dots to make a 10. If an interactive board is used, the teacher may want to move the actual dots. Highlight that although we moved the dots around, we never added more dots and we never took any dots away so the sum remains the same (Slide 8).

  7. The teacher will repeat step 5 with five more sets of Quick Images (Slides 9, 11, 13, 15, and 17).
  8. After scribing the students' strategies, the teacher will make note of the strategies the students used using the Checklist/Notes Doc.
  9. After the final Quick Image, the class will discuss the activity. The teacher will ask the students the following questions, "What made the problems hard?"  "What made the problems easy?" "Which strategies were most efficient for this type of problem or for these numbers?" (Slide 19)
  10. The teacher will close the lesson by summarizing how to make numbers within an addition equation friendly to add (Slide 20).
Assessment Strategies:

After scribing the students' strategies, the teacher will make note of the strategies the students used using the Checklist/Notes Doc.


Advanced Preparation:

  1. If the teacher does not have a projector, the slides for the Quick Images will need to be printed.
  2. If the teacher chooses, he or she may want to scribe student strategies on chart paper or a whiteboard. Chart paper will need to be gathered or an area on the Whiteboard will have to be cleared.
Variation Tips (optional):

The teacher may elect to print the Quick Images on an 8.5 x 11 sheet of paper and present the images using a paper copy.

If the instruction is occurring online, the teacher will want to use the Slides presentation in editor mode. The teacher will minimize the notes so the slide takes up most of the screen. The teacher will present his or her screen to the students. In editor mode, the teacher can move the dots as the students describe their strategy.
