Districts are encouraged to customize this lesson by supplementing with districtapproved resources, materials, and activities to best meet the needs of learners. The duration for this lesson is only a recommendation, and districts may modify the time frame to meet students needs. To better understand how your district is implementing CSCOPE lessons, please contact your child s teacher. (For your convenience, please find linked the TEA Commissioner s List of State Board of Education Approved Instructional Resources and Midcycle State Adopted Instructional Materials.) Lesson Synopsis: Students develop flexible, spontaneous applications of basic fact strategies in a variety of contexts and representations. Students solve, explain, and justify solutions in problems which involve data within bar-type graphs and a variety of real-world contexts. TEKS: The Texas Essential Knowledge and Skills (TEKS) listed below are the standards adopted by the State Board of Education, which are required by Texas law. Any standard that has a strike-through (e.g. sample phrase) indicates that portion of the standard is taught in a previous or subsequent unit. The TEKS are available on the Texas Education Agency website at Number, operation, and quantitative reasoning.. The student recognizes and solves problems in addition and subtraction situations. The student is expected to: 1.3A Model and create addition and subtraction problem situations with concrete objects and write corresponding number sentences. 1.3B Use concrete and pictorial models to apply basic addition and subtraction facts (up to = 18 and 18 9 = 9) Probability and statistics.. The student uses information from organized data. The student is expected to: 1.10A Draw conclusions and answer questions using information organized in real-object graphs, picture graphs, and bar-type graphs. Underlying Processes and Mathematical Tools TEKS: page 1 of 70

2 1.11 Underlying processes and mathematical tools.. The student applies Grade 1 mathematics to solve problems connected to everyday experiences and activities in and outside of school. The student is expected to: 1.11A Identify mathematics in everyday situations. 1.11B Solve problems with guidance that incorporates the processes of understanding the problem, making a plan, carrying out the plan, and evaluating the solution for reasonableness. 1.11C Select or develop an appropriate problem-solving plan or strategy including drawing a picture, looking for a pattern, systematic guessing and checking, or acting it out in order to solve a problem. 1.11D Use tools such as real objects, manipulatives, and technology to solve problems Underlying processes and mathematical tools..

3 Grade 01 Mathematics Unit 15 PI 01 Provide concrete objects or manipulatives for students, and orally present a variety of real-life situations such as: Our class library has 7 books about spiders. The PTO donated 4 more. How many books about spiders are in the class library now? Seventeen students are creating patterns in the math center. Some of the students finished their patterns and returned to their desk. Now there are 8 students in the math center. How many students returned to their desk? How many Valentine s Day cards would Jim need if there are 9 girls and 6 boys in his class? Tricia s dad made two pepperoni pizzas for the class. He put 8 slices of pepperoni on one pizza. He put 5 slices of pepperoni and 9 slices of mushrooms on the other. How many pepperoni slices did he put on both pizzas? Norman and Jesse brought Pokémon cards to school. Norman brought 5 cards, and Jesse brought 8 cards. How many cards do they have in all? Examine the bar type graph, and use the data in the graph to justify the teacher s decision to purchase a total of 14 cupcakes for the class party. Select an appropriate problem-solving plan or strategy to find a solution for each problem. Record a number sentence, a representation of your model, and the basic fact strategy used in the solution process. Orally justify if your answer is reasonable. Standard(s): 1.3A, 1.3B, 1.10A, 1.11A, 1.11B, 1.11C, 1.11D, 1.12A, 1.12B, 1.13 ELPS ELPS.c.3H, ELPS.c.5F page 3 of 70

4 Key Understanding(s): Mathematical knowledge is built through addition and subtraction problem-solving involving everyday situations and by communicating the solution process. When solving a real-life problem, the process includes understanding the problem, making a plan, carrying out the plan, and evaluating the solution for reasonableness. Related addition and subtraction sentences can be used to identify patterns in fact families. Related facts provide a quick and efficient method to compute addition and subtraction situations. Sets can be combined in any order, and the sum will remain the same. Thinking addition is an effective approach to solving subtraction facts. Addition and subtraction problems can be represented with number sentences, expressed using models, symbols, words, and illustrations, and solved using various strategies. Patterns can be used to make predictions and solve problems. Patterns show relationships that help us understand and predict solutions to future problems. Real-object graphs are used for sorting and displaying information where each picture or cell represents one piece of data. Data from everyday situations can be collected, organized, and displayed in a real-object graph. Data within a real-object graph can be compared visually and numerically. Information from a real-object graph can be expressed using words or numbers. Information from a real-object graph can be examined to answer questions and justify solutions.
