GRADE ONE MATHEMATICS - COMMON CORE STANDARDS

In Grade One, students will work with whole numbers and place value— including grouping numbers into tens and ones as they learn to add and subtract up through 20. Students will also use tools and strategies to solve problems.

Activities in these areas will include:

• Quickly and accurately adding numbers together that total up to 10 or less and subtracting from numbers up through 10
• Understanding the rules of addition and subtraction (for example, 5+2=2+5)
• Solving word problems that involve adding or subtracting numbers up through 20
• Understanding what the different digits mean in two-digit numbers (place value) • Comparing two-digit numbers using the symbols > (more than), = (equal to) and < (less than)
• Understanding the meaning of the equal sign (=) and determining if statements involving addition and subtraction are true or false (for example, which of the following statements are true? 3+3=6, 4+1=5+2)
• Adding one- and two-digit numbers together
• Measuring the lengths of objects using a shorter object as a unit of length
• Putting objects in order from longest to shortest or shortest to longest
• Organizing objects into categories and comparing the number of objects in different categories
• Dividing circles and rectangles into halves and quarters

The Grade One math curriculum will incorporate the Standards for Mathematical Practice that will support the Common Core State Standards.

This overview for Mathematics, provided by the Council of the Great City Schools, reflects how the Common Core State Standards have guided our development of a rich and comprehensive curriculum for our students. • Our Mission:
• To provide innovative learning experiences which empower each student to excel and make a difference in a diverse and interconnected world.
