What signature techniques does Molly Lynch recommend for introducing mental math to primary students?

Mental Math and Number Sense: This involves helping students develop a sense of numbers and their relationships. Mental math is used to practice and check their work, boosting their confidence in understanding numbers and operations.

Ten-Frame Mental Math: This method helps students visualize numbers using ten frames or dots to represent numbers from 0-9. It's particularly effective for visual learners.

Number Line Mental Math: Students can create their own number line using index cards or paper. They can then use the number line to practice addition and subtraction within 10.

Math Warm Up & Morning Work: Before starting a lesson, Molly suggests writing a few mental math problems on the board for students to solve. This warms up their math brains and gets them ready for the lesson.

Number Train: This is a mental math game that helps students learn their number facts. Students take turns calling out the next number in a sequence that is 9 more or less than the previous number.
