  1. Transitioning to the Common Core State Standards – Mathematics4th Grade Session 3 Pam Hutchison pam.ucdmp@gmail.com

  2. AGENDA • Multi-Step and Other Word Problems • Review Math Practice Standards • Fractions and Decimals • Lines, Line Segments, Angles and Rays • What’s an Angle • Classifying Angles • Measuring Angles • Data and Line Plots

  3. Multi-Step Word Problems A pair of hippos weighed 5,201 kg together. The female weighed 2,038 kg. How much more did the male weigh than the female?

  4. Multi-Step Word Problems A copper wire was 240 m long. After 60 m was cut off, it was double the length of a steel wire. How much longer was the copper wire than the steel wire at first?

  5. Multi-Step Word Problems Jennifer has 256 pink beads. Stella has 3 times as many beads as Jennifer. Tiah has 104 more beads than Stella. How many beads does Tiah have?

  6. Multi-Step Word Problems Sandy’s garden has 42 plants in each row. She has 2 rows of yellow corn and 20 rows of white corn. How many plants does she have?

  7. CCSS Mathematical Practices REASONING AND EXPLAINING 2. Reason abstractly and quantitatively 3. Construct viable arguments and critique the reasoning of others OVERARCHING HABITS OF MIND 1. Make sense of problems and perseveres in solving them 6. Attend to precision MODELING AND USING TOOLS 4. Model with mathematics 5. Use appropriate tools strategically SEEING STRUCTURE AND GENERALIZING 7. Look for and make use of structure 8. Look for and express regularity in repeated reasoning

  8. Math Practice Standards Using the MP descriptions from the 4th Grade Flipbook, describe how you are developing each of these practices in your students. • Be ready to share an example for each of the 8 Math Practices Standards. • Which standard is the hardest to implement?

  9. 4.NF.5 Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100. (Students who can generate equivalent fractions can develop strategies for adding fractions with unlike denominators in general. But addition and subtraction with unlike denominators in general is not a requirement at this grade.)

  10. 4.NF.5 • Focus on working with grids, number lines and other models (not algorithms) • Base ten blocks and other place value models can be used to explore the relationship between fractions with denominators of 10 and denominators of 100 • This work lays the foundation for decimal operations in fifth grade.

  11. 3 tenths = 30 hundredths 0.3 = 0.30 =

  13. 57 hundredths 5 tenths + 7 hundredths =

  15. 4.NF.6 Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.

  16. 4.NF.6 • Focus on connections between fractions with denominators of 10 and 100 and the place value chart. • Connect tenths and hundredths to place value chart • Connect to 0.32 to

  17. 4.NF.6 • Students connect with 0.32 and represent it on a place value model.

  18. 4.NF.7 Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.

  19. Planning a Lesson Connecting fractions, decimals, and place value. • Review • Name the fractions • Tenths grid • Hundredths grid • Number line – tenths and hundredths • Write in expanded form

  20. Planning a Lesson • Word Problem: In the school chorus, of the students are girls. If there are 10 boys in the chorus, how many girls are there?

  21. Place Value Hundreds Tens Ones

  22. Place Value Hundreds Tens Ones

  23. Place Value Hundreds Tens Ones

  24. Place Value Hundreds Tens Ones

  25. Place Value Ones Tenths

  26. Decimal Place Value Ones Tenths

  27. Decimal Place Value Ones Tenths Hundredths

  28. Fractions and Decimals • So we can name some fractions as decimals • How do we know which fractions we can also name as decimals?

  29. Fractions and Decimals • How do we know which fractions we can also name as decimals? • When the denominator is a place value number (also called a power of 10)

  30. Fractions and Decimals • For example: can also be written as 0.3 can also be written as 0.72 • What about ?

  31. Classwork • See Fractions and Decimals worksheet

  32. Engage NY • Fluency Practice • Designed to promote automaticity of key concepts • Daily Math is another form of fluency practice • Application Problem • Designed to help students understand how to choose and apply the correct mathematics concept to solve real world problems • Read-Draw-Write (RDW): Read the problem, draw and label, write a number sentence, and write a word sentence

  33. Engage NY • Concept Development • Major portion of instruction • Deliberate progression of material, from concrete to pictorial to abstract • Student Debrief • Students analyze the learning that occurred • Help them make connections between parts of the lesson, concepts, strategies, and tools on their own

  34. Engage NY Module 5 Lesson 28 • MD.4 Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots. For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection.
