Learn powerful subtraction strategies in this fun and approachable class, built on research-based and tested strategies that help kids slowly develop strong mathematical reasoning skills. Students who are looking for extra practice, who feel lost in math class, or who want to grow their brains and feel challenged will benefit from this class! In every class, we will engage in a series of subtraction problems that build on prior knowledge and help us to solve more complex problems. The subtraction problems are intentionally created to develop deep understanding and reinforce powerful strategies that build students' confidence and flexibility with numbers. Kids can join this class at any point! Participate and share your thinking and listen to other kids reason and think about the problems. This is a safe and fun space to think and grow! Listening to others is a powerful way to acquire new ideas, strategies and skills. Teacher-created visuals and models will reinforce our thinking and help students to visualize the numbers. Receive the number problems after class and try them on your friends and family! Students can expect to learn powerful strategies for: - Single-digit subtraction - Making friendly numbers - Teens - A number -9 - Doubles -1 - Doubles -2 - Subtaction of 10s, 100s, 1000s **Algorithms are incredible mathematical inventions but not great teaching tools. First, we will build a deep understanding of addition, subtraction, place value, and reasoning. Once kids understand numbers deeply and how to compose and decompose those numbers, algorithms will feel easy and natural!
學習目標
Students will develop a deep understanding of strategies used to subtract numbers that can be applied to other problem-solving situations. They will use what they already know to form relationships and see numbers in a more meaningful way. Students will be able to increase their ability to solve mental math problems and gain confidence in approaching unfamiliar subtraction problems with their new-found knowledge and skills.

I currently work as an Elementary Math Consultant, supporting teachers and students in implementing strategic math programs that support diverse learners at all skill and ability levels. My focus is on numeracy intervention, where I create resources, games, instructional routines, and assessments for students who have been identified as at-risk in foundational numeracy skills. 評論
