Cognitively Guided Instruction - Anticipatory Framework School: Dunwoody Springs Problem Type JRU Problem Teacher: Kimberly Wood JRU SRU PPW-WU CDU M JCU SCU CQU MD JSU SSU PPW-PU CRU PD I have 3 red pencils and 4 blue pencils. Simon has 5 red pencils and 2 blue pencils. We have the same amount of pencils.” Show me how this statement is true or not true. Grade: 1st Date: Rationale/Goals (Why are you asking this problem type with these particular numbers?): Students have been working on math fluency. They have solved basic addition and subtraction problems, word problems, and problems with missing numbers. The next step is for students to understand the meaning of the equal sign and prove if a number sentence is true or false based on their knowledge of what the equal sign means.

Smith Cognitively Guided Instruction - Observation Framework No Base-Ten Evidence Direct Modeling Strategies 1. Counting Strategies Counts all Jonathan drew a picture for 3+4 and a picture for 5+2. He then counted all of the circles to realize the equations were true. 1. One ten as a unit 4. Collects tens and ones 2. More than one ten as a unit 5. Counts tens as ones 3. Direct Place Value Explanation 6. Increments by tens Alaiya drew a picture for each side of the equation and counted all of the circles. She made a mistake in counting her circles and did not complete the problem correctly because of this. Diajonae also drew a picture for both sides of the equation and counted all the circles correctly. 2. Counts from first 3. Counts from larger 1. Counts on from first 7a. Counts on from first Xavier started counting from the first number. For 3+4, he started at three and counted up four times using his fingers to keep track. For 5+2, he started at five and counted up two times using his fingers to keep track. 2. Counts on from larger 8. Combining Tens and Ones Invented Algorithm 7b. Counts on from larger 11. Compensating Invented Algorithm Incrementing Invented Algorithm 9. Combines tens then increments 10.

Smith Reflection (What did I learn as a result of this lesson? What did I observe that corresponded with my anticipatory framework? What did I not anticipate? What are my next steps? How will this guide my instruction?) I learned that the students that participated in this problem depended highly on direct modeling. The students could have used counting or derived facts strategies to solve these problems more quickly. I did observe that the students were able to understand the meaning of the equal sign. All students solved both sides instead of recording the answer to the left side on the right side of the equation. Direct modeling was the strategy that I observed the most that corresponded with my anticipatory framework. One student did use a counting by one strategy to solve the problem that I had anticipated prior to the lesson. On the anticipatory framework, I recorded base ten strategies, invented algorithms, and derived facts strategies, but I did not see my students use these. My next steps would be to use large numbers. I would be curious to see if the students used other strategies than direct modeling. I will use this knowledge to guide my instruction on solving problems in different ways. Students are currently working on math fluency, so I want to be sure that they are applying this knowledge to when they are solving problems. * Indicates use of combinations in 10 to make a model for ones from a stick of ten (e.g., breaks off 3 from 10 to make 7) © 2008-2012 Stephanie Z.
