DESCRIPTION
TRANSCRIPT
The following slides are my team’s version of lesson plans for the math topic of study.
They are shared as suggestions ONLY…please consider sharing your plans on the dropbox...
we’d love to see how other teachers are using the program
We use some of these slides during our lessons to incorporate different math practices as we do
number talks to help our students practice on skills they need to develop. Other slides are included to
be used as stations or games. Please adjust and use these plans as you would like
or toss them in the trash

Grade 2 ~ Math Topic Two: Understanding Addition StrategiesTime Line: August 20 – August 29, 2014
CCSSM: Operations and Algebraic Thinking2.OA.1. Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.2.OA.2 Fluently add and subtract within 20 using mental strategies.(1.OA.A.6~Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13). Number and Operation in Base Ten2.NBT.5. Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.2.NBT.9. Explain why additions and subtraction strategies work, using place value and the properties of operations.
Mathematical Practices#1 Make sense of problems and persevere when solving them.#6 Attend to precision.#7 Look for and make use of structure.
Learning Targets*I can choose when to use addition or subtraction in a word problem.*I can represent addition or subtraction word problems using objects, drawings, and equations with unknowns in all positions.*I can add and subtract numbers within 100 with ease by applying strategies (decomposing numbers into tens and ones, using commutative and associative properties) based on the numbers being added subtracted.
Learning TargetsI can choose when to use addition or subtraction in a word problem.I can represent addition or subtraction word problems using objects, drawings, and equations with unknowns in all positions.I can use mental strategies to add or subtract numbers within 20 with ease. I can recall from memory all sums of two one digit numbers.I can add and subtract numbers within 100 with ease by applying strategies based on the numbers being added or subtracted.I can explain addition or subtraction using place value.I can explain addition and subtraction using the properties of operation.
VocabularyDoubles, near doubles, addend, number sentence, part-part-whole
Math ToolsNumber line, base ten blocks, tens frame, hundreds chart, counters, cubes, part-part-whole, flash cards

Topic 2.1- Adding 0,1,2 TM pg. 35A-35BFocus: How are the number relationships of 0-more than, 1-more-than, and 2-more-than the basis for adding with 0,1, and 2?see Tina’s suggestions below…
Lesson
Topic 2.1- Adding 0,1,2 TM pg. 35A-35BFocus: How are the number relationships of 0-more than, 1-more-than, and 2-more-than the basis for adding with 0,1, and 2? Complete the 2.1 topic newspaper for guided practice. Math magic square for zero- group activity Two more/ game on computer:http://www.bgfl.org/bgfl/custom/resources_ftp/client_ftp/ks1/maths/two_more/ Independent practice: Workbook page or extra page. Require students to circle the 0, 1, or 2 so they know what they are adding to the number and follow the pattern they discovered on the initial activity.
Give students a work mat and counters. Have them put zero counters in the zero box, one counter in the ones box, and two counters in the twos box. Have them put out a set number of counters. Ask them if they took that number or part and added 0 counters to that what would be the whole. Then have them add one counter to that number to find out the whole, then two numbers to find the whole. Have them discuss their answers and see the pattern. Continue in this way till students see a pattern when adding zero to a number, one to a number and two to a number.

Topic 2.2- Adding DoublesFocus: What are different ways to learn and remember doubles facts? See Tina’s suggestions
Lesson
Topic 2.2- Adding DoublesFocus: What are different ways to learn and remember doubles facts? Discuss with students what numbers are added with a doubles fact? Why are they called doubles facts? Ask them what other doubles facts they know and have them list the other facts. Use counters and part-part- whole work mat that was run previously, to show how students can create doubles using counters. Ask them how to show double 4. Put down five counters on one side and have them show you how to make it a double. Use the newspaper for guided practice. Independent practice is the workbook page.

remember to add s after http to play at school
fishing for doubles
FridayAug. 22
Topic 2.3- Near DoublesFocus: How can doubles facts be used to learn near doubles facts?
Topic 2.3- Near DoublesFocus: How can doubles facts be used to learn near doubles facts? Ask 10 children to form 2 rows of 5. Children should stand side by side or in pairs. What doubles fact tells you how many children are here? Ask 1 more child to join one of the lines. What addition sentence can I write to show this? This is called a near double. Use the newspaper as guided practice. Independent practice: workbook page
Have students use two different color cubes to add doubles and add one. Write an addition equation to show the double and the double plus one.
I have a game with dice and game board to practice doubles plus one. I also have a matching activity with a sheet students can record their answers.

Topic 2.4 Adding in any orderFocus: What happens to the sum of two numbers when the order of the numbers being added is changed?Check Tina’s suggestions
Lesson
Topic 2.4 Adding in any orderFocus: What happens to the sum of two numbers when the order of the numbers being added is changed? I am going to write two math problems and example 3+4=7 and 4+3=7. I am going to have them write down what the difference is and have them explain to me what they know about these two addition problems. We are going to discuss this. Students are going to show how to create these two addition sentences with connecting cubes of two different colors. Complete the newsletter as guided practice.
Students practice with partners and number cubes. Roll two number cubes. Write down the addition equation. Then switch the order of the addition equation. Record this on their sheet
