Unit 3 is typically a seven-week unit taught in January and February.
Mathematics is a tool used to solve problems in everyday life. In this unit, students use their developing knowledge of patterns and relationships, as well as their understanding of mathematical language, to learn how mathematics is used in everyday life.
In Grade 3, students worked with common fractions in concrete and pictorial forms. Their experience with decimals was also concrete, using money to learn about quantities less than one. While continuing to develop conceptual understanding through models and pictures, students in Grade 4 move to more abstract thinking about common and decimal fractions. They look at the relationship between common and decimal fractions and at how to perform some of the basic number operations with fractional parts. These understandings are extended in Grade 5 as students learn about operations with unlike denominators and percents.
Previously students expressed the likelihood of an event with words such as certain, more likely, equally likely, less likely, and impossible. In Grade 4, students apply their understanding of fractions to the concept of probability, as they learn to quantify the probability of an event. This unit also focuses on organizing and listing possible outcomes of an event. The instructional sequence lays the foundation for learning about ratios in Grade 5.
