Unit 6 is typically a four-week unit taught in May and June.
Mathematics is a language consisting of carefully defined terms and symbols. Learning algebra means learning a language to describe relationships and functions. This language can be a problem, a table, a graph, an expression, an equation, or a function.
An important part of understanding the language of algebra is learning notations, conventions, and mathematical properties. In Grade 4, students learned that unknown quantities can be represented with letters or shapes. They explored the concept of variable as a specific quantity and as a varying quantity. Grade 5 students write and evaluate expressions in one variable using substitution and knowledge of number properties. Students work with problems that provide them with opportunities to understand the need for a unique answer and the need for rules that are required to achieve a unique answer. They investigate computational procedures using order of operations and number properties. Students use symbols to represent a situation, recognize equivalence, and use inverses or “opposite operations” to solve equations.
Probability measures the likelihood of an event and is applied to situations for which the outcome cannot be absolutely determined in advance. Chance situations may have uncertain outcomes for individual trials, but follow a regular pattern over many trials. In Grade 4, students used organized lists and tree diagrams to determine all possible outcomes of experiments. They applied their understanding of fractions to the concept of probability, as they learned to quantify the probability of an event. In this unit, students apply number concepts such as ratios and fractions to describe the probability of an event as they explore concepts of experimental and theoretical probability. Students make predictions based on the results of experiments and express probability of an event as a fraction or a ratio. These explorations prepare students to determine and compare experimental and theoretical probabilities in Math A. Experimental probabilities are based on the results of an experiment. Theoretical probabilities are based on the sample space or possible outcomes of an experiment.
