了解事實 K-1 年級：20 以內的數數、加法和減法

Get Your Facts Straight: Addition and Subtraction within 20 is a positive, fun, interactive class based on the Singapore philosophy of problem-solving and deep-mathematical thinking. Participants interact with each other and the teacher.  Students will use manipulatives, drawing, games, and expressions and equations to practice addition and subtraction within 20.  This class is appropriate for students who have strong Kindergarten experience with math foundations such as count sequence, using fingers and objects to count, writing numbers, and fluency or near-fluency with simple addition and subtraction within 10. If your learner is getting ready for Kindergarten, please see the previous class in this sequence.

Sessions are structured to be engaging, fun, interactive, and short (for young attention spans). Although the focus is on addition and subtraction within 20, we also focus on other Kindergarten (and some Grade 1) math standards. Classes will cycle through continuously. 

Each week includes: Addition and subtraction within 20 
Learners will practice composing numbers within 20 through addition and subtraction. Supplies: writing materials and counters.

Each daily session includes:
- Math story problem and discussion 
- Interactive math activity (examples include: counting, composing and decomposing numbers, number/quantity identification, comparing numbers, making 10, and identifying patterns)
- A fun group math game via whiteboard
