Our new set of Task Cards on probability for children ages 9-12 are thoughtfully divided into six sections, each focusing on different aspects of understanding probability. These sections provide a structured approach to learning, encouraging learners to engage with concepts through practical examples and reflective questions. In this post, we provide an overview of each section to demonstrate how the set is scaffolded and engaging!
1-Introduction to Probability
![Probability Task Cards](https://i0.wp.com/alisonsmontessori.blog/wp-content/uploads/2024/07/20240725_183113.jpg?resize=1020%2C1020&ssl=1)
The Introduction to Probability section lays the foundation for understanding probability. It includes questions such as, “What is the chance of snow tomorrow if the weather forecast says ‘sunny’ and temperature of 90°F?” and “You pick a gummy bear from a bag. It can be red, orange, or yellow. Is it certain you’ll pick a red one?” These questions help students grasp basic probability concepts by relating them to everyday scenarios. The cards aim to clarify the meaning of probability and certainty, setting the stage for more complex topics.
2-Events and Outcomes

In the Events and Outcomes section, learners are encouraged to think about different possible results of simple actions. For example, they are asked to list all possible outcomes of flipping a coin or rolling a die. This section helps children understand that events can have multiple outcomes, and it introduces the concept of fair and unfair scenarios. One card asks, “You flip a coin to decide who goes first between two people. Is this fair?” This stimulates critical thinking about fairness and randomness.
3-Fair and Unfair Games

The Fair and Unfair Games section deals with the concept of fairness in probability. It includes scenarios involving spinners with different-sized slices, asking students to consider whether the probabilities are the same for each color. This section is designed to help students identify and understand biases in probability, making them aware that not all games or situations are inherently fair. Describing fair games and understanding why they are fair is a key focus.
4-Sample Space and Probability

In the Sample Space and Probability section, children learn about the total possible outcomes (sample space) of an event and how to calculate probabilities. For instance, they might be asked to list all possible outcomes of rolling a die or flipping a coin and then determine the probability of each outcome. This section emphasizes the mathematical side of probability, teaching learners to use fractions and ratios to express probabilities accurately.
5-Representing Probability

The Representing Probability section focuses on different ways to represent probability, such as fractions and percentages. Learners might be asked to explain why certain representations are used and how to convert between them. This section helps learners understand the versatility of probability expressions and prepares them for more advanced mathematical concepts.
6-Word Problems

Finally, the Word Problems section applies probability concepts to real-world scenarios. Children are presented with various problems that require them to calculate probabilities based on given information. For example, they might have to determine the probability of picking a red marble from a bag or the chances of different outcomes when rolling dice. This section is designed to reinforce students’ understanding and application of probability through practical problem-solving exercises.
We would recommend you provide your learners with tools such as a die, a coin, a spinner, and a bag with marbles. This way, they can experience probability in a concrete manner. Our task cards will provide the opportunities to roll a die, flip a coin, and pick a marble out of a bag, which will demonstrate that probability can be calculated based on predictable outcomes!
