At Williams we use GO Math as our core math program as well as Every Day Math Calendar. GO Math is aligned with the Common Core State Standards. Through the use of daily, hands-on math lessons student are taught the fundamental math skills of operations and algebraic thinking, numbers and operations in base ten, measurement and data, and Geometry. Every Day Math Calendar is a supplemental math program that is used daily through morning meeting.

Below is a link to view the grade 1 standards that your child will be held accountable for by the end of first grade.

Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.
