  1. THIRD GRADESession 2 Vacaville USD November 3, 2014

  2. AGENDA • Problem Solving and Patterns • Math Practice Standards and High Leverage Instructional Practices • Number Talks • Computation Strategies • Word Problems • Number Lines • Elapsed Time • Multiplication

  3. Expectations • We are each responsible for our own learning and for the learning of the group. • We respect each others learning styles and work together to make this time successful for everyone. • We value the opinions and knowledge of all participants.

  4. Cubes in a Line How many face units can you see when cubes are put together?

  5. Cubes in a Row • How many face units do you see on 1 cube?

  6. Cubes in a Row • How many face units do you see on 2 cubes? • How can you keep track of what sides you have counted?

  7. Cubes in a Row • You are going to be given 2 strips of paper like this: _____________ _____________ number of cubes number of face units 7

  8. Cubes in a Row • What patterns do you see? • How could those patterns help you figure out how many face units there would be?

  9. Math Practice Standards • Remember the 8 Standards for Mathematical Practice • Which of those standards would be addressed by using a problem such as this?

  10. CCSS Mathematical Practices REASONING AND EXPLAINING Reason abstractly and quantitatively Construct viable arguments and critique the reasoning of others MODELING AND USING TOOLS Model with mathematics Use appropriate tools strategically OVERARCHING HABITS OF MIND Make sense of problems and persevere in solving them Attend to precision SEEING STRUCTURE AND GENERALIZING Look for and make use of structure Look for and express regularity in repeated reasoning

  11. High Leverage Instructional Practices

  12. High-Leverage Mathematics Instructional Practices An instructional emphasis that approaches mathematics learning as problem solving. • Make sense of problems and persevere in solving them.

  13. An instructional emphasis on cognitively demanding conceptual tasks that encourages all students to remain engaged in the task without watering down the expectation level (maintaining cognitive demand) • Make sense of problems and persevere in solving them.

  14. Instruction that places the highest value on student understanding • Make sense of problems and persevere in solving them. • Reason abstractly and quantitatively

  15. Instruction that emphasizes the discussion of alternative strategies • Construct viable arguments and critique the reasoning of others

  16. Instruction that includes extensive mathematics discussion (math talk) generated through effective teacher questioning • Reason abstractly and quantitatively • Construct viable arguments and critique the reasoning of others • Attend to precision • Look for and make use of structure • Look for and express regularity in repeated reasoning

  17. Teacher and student explanations to support strategies and conjectures • Reason abstractly and quantitatively • Construct viable arguments and critique the reasoning of others

  18. The use of multiple representations • Make sense of problems and persevere in solving them. • Model with mathematics • Use appropriate tools strategically

  19. Number Talks

  20. What is a Number Talk? • Also called Math Talks • A strategy for helping students develop a deeper understanding of mathematics • Learn to reason quantitatively • Develop number sense • Check for reasonableness • Number Talks by Sherry Parrish

  21. What is Number Talk? • A pivotal vehicle for developing efficient, flexible, and accurate computation strategies that build upon key foundational ideas of mathematics such as • Composition and decomposition of numbers • Our system of tens • The application of properties

  22. Key Components • Classroom environment/community • Classroom discussions • Teacher’s role • Mental math • Purposeful computation problems

  23. Classroom Discussions • What are the benefits of sharing and discussing computation strategies?

  24. Students have the opportunity to: • Clarify their own thinking • Consider and test other strategies to see if they are mathematically logical • Investigate and apply mathematical relationships • Build a repertoire of efficient strategies • Make decisions about choosing efficient strategies for specific problems

  25. 5 Goals for Math Classrooms • Number sense • Place Value • Fluency • Properties • Connecting mathematical ideas

  26. Clip 3.2 – 3rd Grade Addition: 59 + 13 • Before we watch the clip, talk at your tables • What possible student strategies might you see? • How might you record them?

  27. How do the student strategies demonstrate number sense? • What evidence is there that the students understand place value? • What examples of properties can be observed in the strategies/discussions? • How does the teacher connect math ideas throughout the talk?

  28. Clip 3.4 – 3rd Grade Subtraction: 70 – 34 • Before we watch the clip, talk at your tables • What possible student strategies might you see? • How might you record them?

  29. Do you see evidence of students demonstrating: • Number sense • Place Value • Fluency • Properties • Connecting mathematical ideas

  30. Solving Word Problems

  31. 3 Benefits of Real Life Contents • Engages students in mathematics that is relevant to them • Attaches meaning to numbers • Helps students access the mathematics.

  32. Mr. Alvarez drove 233 miles to get 500 baseballs on Monday. On Friday Mr. Alvarez drove 987 miles. How many total miles did Mr. Alvarez drive?

  33. There were 333 children in a spelling contest. Of those, 219 were girls. How many more girls than boys were in the spelling contest?

  34. Three friends go apple picking. They pick 13 apples on Saturday and 14 apples on Sunday. They share the apples equally. How many apples does each person get?

  35. Jason earns $6 per week for doing all his chores. On the fifth week he forgets to take out the trash so he only earns $4. How much did Jason earn in 5 weeks?

  36. Using an Open Number Line

  37. A cricket jumped 7 centimeters forward and 12 centimeters back then stopped. If the cricket started at 27 on the ruler, where did the cricket stop?

  38. James and Chloe each have pet snakes. James’ snake is 35 centimeters long. Chloe's snake is 7 centimeters longer than James’. How long is Chloe's snake?

  39. Bill throws his baseball 41 feet, which was 14 feet farther than Samantha threw her baseball. How far did Samantha throw her baseball?

  40. Mei’s frog leaped forward 34 centimeters. Then it leaped forward some more. In all, it leaped 61 centimeters. How far did Mei’s frog leap the second time?

  41. Halle has two ribbons. The blue ribbon is 58 cm long. The green ribbon is 83 cm long. How much longer is the green ribbon?

  42. Elapsed Time

  43. We started math at 10:15 a.m. We worked for 23 minutes. What time was it when we ended?

  44. The soccer game started at 11:45 and lasted 52 minutes. What time did it end?

  45. Leslie starts reading at 11:24 a.m. She finishes reading at 11:57 a.m. How many minutes does she read?
