9th Grade Math Proficiency Test - Question No. 36
A box of doughnuts contains 4 glazed, 3 cream-filled, and 2 jelly doughnuts. What is the probability of getting a cream-filled doughnut, eating it, and then getting a glazed doughnut? A detailed answer is provided.
Birthday Problem
This activity discusses the probability of at least two matching birthdays in a small group of people. It includes an online program that creates a set of dates at random.
Grade One: Use guess and check to solve problems North Carolina Department of Public Instruction Mathematics Curriculum Competency Goal 5: Mathematical reasoning, problem solving. Lesson Plans: Give student a problem in which the answer could be several combinations. Show student six toys with imaginary weights indicated. Judy packed three toys into a box. The package weighed 15 pounds. What three toys did she pack? Place dominoes on the "donut" so that all sides equal 10 (or other appropriate numbers).
Grade One: Explore combinations for numbers to 10 North Carolina Department of Public Instruction Mathematics Curriculum Competency Goal 7: Compute using whole numbers. Lesson Plans: Give student ten counters. Ask child to show three different ways to put them into two sets. "What number sentences are you showing? Are there any other ways to arrange them?" Ask student to show all of the ways to make 10. Have the child to arrange the models in some organized fashion and to explain what has been done. The activity should be repeated many times as a math lesson using many different materials. For example, use two colors of pattern blocks or Unifix cubes, use toothpicks (position would determine addends), glue paper Squares in two colors or two colors of cereal, etc.
Grade Two: Use drawings/diagrams/organized lists to solve problems North Carolina Department of Public Instruction Mathematics Curriculum Competency Goal 5: Mathematical reasoning, problem solving. Lesson Plans: Give student a problem that involves finding all possibilities. Observe how the student finds the solution. For example, "There are four girls in the tournament. How many possible two people teams could be set up? The girls - Sue, Jill, Maria, and Keiko - all work well together." With a partner, ask students to make a chart to show what possible combinations of stamps you could purchase from the machine that holds $0.02 stamps, $0.03 stamps, and $0.05 stamps if you have only $0.12.
