  1. Fifth Grade Decimal Workshop

  2. Objective Teachers will have a deeper understanding of the Decimal Domain of the Common Core. They will demonstrate their understanding through their struggle of working through the given activities and through the use of precise language when sharing their thinking.

  3. Introducing Activity • Put ( * ) next to what you are sure of • Put ( ? ) next to what you are unsure • Put an (X) next what you do not understand

  4. Congruent figures have the same area.

  5. The Focus is Area and not the Shape

  6. What fraction is represented by the following shaded area?

  7. National Library of Virtual Manipulatives • Fractions Visualizing • http://nlvm.usu.edu/en/nav/category_g_2_t_1.html

  8. The Fat Inch • Directions

  9. Comparison • Same Numerator • Same Denominator • Compare to a benchmark

  10. Counting with unit Fraction

  11. Foundation is still the unit .6 = .1 + .1 + .1 +.1 + .1 +.1

  12. Decomposition of Number is still a Foundation 1 = .1 + .9 1 = .2 + .8

  13. Equivalence by Subdividing

  14. Work with base 10 Blocks • Spend time discussing and creating 2 activities you can use in your class with the Base 10 blocks. • Creating a Number • Inequality • …

  15. Connect to the Numberline

  16. Prove using Base 10 Blocks

  17. Prove using the Number line If then .6 = .60

  18. Addition

  19. Adjective Noun Connection 3 tenths + 25 hundredths 30 hundredths + 25 hundredths 55 hundredths

  20. Connect to Decimal Addition .3 + .25 = .30 +.25 =.55

  21. Decimal to Fraction

  22. Model and Solve

  23. Model and Solve

  24. Model and Solve

  25. Model and Solve 2.1 +4.39

  26. Model and Solve 3.23 + 5.4 4.8 + 3.26

  27. Model and Solve 5.NBT.7 Base 10 Blocks Based on Place value Properties of Operations Equivalency

  28. Model with Base 10 blocks 3 X 4.2 4.2 + 4.2 + 4.2

  29. Multiplication Area Model Whole Numbers Use graph paper and explain using the distributive property. 14 x 5 13 x 14

  30. Multiplying (Area Model)

  31. What Numerical Expression is being modeled?

  32. What is the numerical Expression being modeled? How would you connect this model to the Distributive property? Build and simplify Your numerical expression.

  33. Using the Area Model Multiply 2.3 X 3.4 3.4 X 4.2

  34. Connect the model to the property • Base 10 to Distributive Property • Connect to the Standard Algorithm

  35. Decimal Division • Only to the hundredths • Focus on measurement Division • Focus on the unit when connecting to the number line
