Topic Family Math Letters & Worked Examples
Family Math is a letter to families that describes the major concepts within various grade level math topics. Each letter uses words and phrases that should be familiar to students from the lessons in the topic. The letters also include visual supports that students can use to help explain the concepts or strategies they are learning in school. Family Math also includes simple and practical at-home activities to extend learning and help students see mathematics in the world.
Clicking on a topic in Grades 1 - 5 will open a Google Folder that contains at least one worked example problem from each lesson. The purpose of these worked examples is to provide parents and students with explicit support for developing understanding of models and strategies that may be unfamiliar. Note that folders can only be accessed by users with a @forsythk12.org account because the worked examples are the property of Great Minds PBC (the publisher of the Eureka Math Squared curriculum).
Parents seeking to access worked examples will need to sign in to ClassLink with their child's login credentials.
Note: The topics listed below are organized in a logical sequence by the approximate time in which they will be taught. Instructional pacing may vary slightly from school to school.
