Worksheets Included:

1. Calculating Probability: Through this worksheet students are given nine scenarios, like spinning a 10 on a 10-section spinner. They will learn to place an arrow on a scale from "impossible" to "certain" and write the probability as a fraction, simplifying where necessary.
2. Compound Events: Students will use the fact that total probabilities equal one to calculate different outcomes and consider mutually exclusive and exhaustive events. Section A: List the probability of events not occurring. Sections B-C: Identify mutually exclusive and exhaustive scenarios. Section D: Calculate probabilities for different outcomes.
3. Evaluating Probability Statements: This worksheet has six statements about probability. Students decide if each is true or false and explain their reasoning. Topics include equal chances, biased coins, and real-life scenarios like birth, dice rolls, and weather. Pair with our probability language worksheets.
4. Expected Outcomes: Students will calculate expected frequencies using theoretical probability. The worksheet has eight questions and answers to match. Topics include wearing glasses and train delays. Probabilities are given as fractions and decimals. Students also calculate event occurrences based on expected frequency.
5. Experimental Probability: In section A, students roll a dice 60 times, record the '6's every 10 rolls, and plot their results on a graph. They compare their results with theoretical probability. In section B, they analyze provided data, plot it, and answer related questions.
6. Probability Ranges (Impossible To Certain): Familiarize students with probability language and the probability scale. Section A: Place nine statements on a scale from impossible to certain. Section B: Evaluate eight statements, like “you will blink today,” using terms like likely, unlikely, and certain. Section C: Create events for each probability term. Follow up with our “Calculating Probability” worksheet.
7. Probability With A Deck Of Cards: This worksheet uses a deck of cards theme to teach probability. Students list probabilities of various outcomes when drawing one card, writing fractions and simplifying them. Examples include red cards, prime clubs, and tens of hearts.
8. Probability With Dice: This worksheet helps students practice writing probabilities as fractions using dice rolls. They will write probabilities for single and combined outcomes, using terms like multiples, factors, primes, squares, and triangle numbers. Students will also mark probabilities on a 0 to 1 scale. Simplify answers.
9. Relative Frequency: This worksheet uses experimental data to calculate relative frequencies and answer questions. Section A: Calculate experimental probabilities from dice and spinner results. Discuss fairness. Section B: Calculate relative frequencies from experiments, considering changes over time. Calculators are required.
10. Sample Space Lists: This worksheet guides students in systematically listing all outcomes. Section A: List outcomes of three single events. Section B: Use the provided tables for three more events. Section C: List outcomes without tables. Section D: Calculate probabilities of different outcomes. Use the product rule for counting to check.
11. Sample Space Tree Diagrams: Students will complete sample space diagrams to find probabilities. Section A: Complete pre-drawn diagrams for adding, multiplying, or subtracting two dice scores. Answer questions about outcomes and probabilities. Section B: Construct sample space diagrams for events like tossing a coin, spinning a spinner, and balls in bags.
12. Tree Diagrams (A): This assignment teaches students to use tree diagrams to list outcomes and calculate probabilities of independent events. There are seven questions about decreasing scaffolding. Students draw tree diagrams and calculate two or three probabilities using fractions and decimals. Calculators are optional.
13. Tree Diagrams (B): This worksheet teaches students to use tree diagrams for dependent events. Section A: Complete three provided tree diagrams and calculate probabilities for scenarios without replacement. Section B: Draw tree diagrams for three conditional events and calculate probabilities. Children need to use fractions and decimals. They can use calculators if they need to.
14. Writing Probability As A Fraction: This worksheet will help your young learners write probabilities as simple fractions in this worksheet. Events include pulling objects from a bag, spinning a spinner, and rolling dice. Some events are impossible. Discuss that probabilities of an event and its opposite add up to one. Simplified answers included.

You can use this worksheet pack for your whole class, small groups, or a mix of both!
