Transcript

  • 1. Math and Mega Pixels 2 nd Grade Nikki Davis March 2, 2010
  • 2. This plant is in the 5 th stage of it’s lifecycle. This is when the flower blooms. For your mom’s birthday you want to get her as many flowers as you can. You can pay for 44 flowers, but your dad said he would pay for 152 flowers. How many flowers will your mom have for her birthday?
  • 3. If you are stuck, try this:
    • Estimate what your answer should be. Will it be more than 100?
    • Use the benchmark of 50 to solve the problem.
    • Use the base ten blocks to figure it out.
  • 4. Baby Grace is in the toddler stage of the human life cycle. I am in the young adult stage of the human life cycle. I am 65 inches tall and Baby Grace is 26 inches tall. How much taller am I then she is?
  • 5. If you are stuck, think about this:
    • Do you need to regroup in order to solve the problem?
    • Estimate the answer. What should the answer be close to?
    • Will a ruler help?
  • 6. Catherine is in the Toddler Stage of the human life cycle. If there are 24 owl eye balls on her pajamas, how many owls are there?
  • 7. If you are stuck, try this:
    • How many eyeballs are on each owl?
    • Draw a picture to solve the problem.
  • 8. In the 5 th stage of the life cycle of a flowering plant, the flowers have bloomed. In the garden, 12 flowers have bloomed. There are 8 anthers in each flower. How many anthers are there in all?
  • 9. If you are stuck, try this:
    • Draw a picture to figure out the answer.
    • Use our lima beans as manipulative to represent each anther.
  • 10. Answers
    • 1. 196 flowers
    • 2. 39 inches tall
    • 3. 12 owls
    • 4. 96 anthers
  • 11. Georgia Performance Standards
    • M2N2. Students will build fluency with multi-digit addition and subtraction.
    • a. Correctly add and subtract two whole numbers up to three digits each with regrouping.
    • b. Understand and use the inverse relation between addition and subtraction to solve problems and check solutions.
    • c. Use mental math strategies such as benchmark numbers to solve problems.
    • d. Use basic properties of addition (commutative, associative, and identity) to simplify problems (e.g. 98 + 17 by taking two from 17 and adding it to the 98 to make 100 and replacing the original problem by the sum 100 + 15).
    • e. Estimate to determine if solutions are reasonable for addition and subtraction.
    • M2N3. Students will understand multiplication, multiply numbers, and verify
    • results.
    • a. Understand multiplication as repeated addition.
    • c. Use the multiplication table (grid) to determine a product of two numbers.
    • d. Use repeated subtraction, equal sharing, and forming equal groups to divide large collections of objects and determine factors for multiplication.
