Students in First Grade are expected to....
Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10 using concrete models or drawings.
Relate the strategy to a written method and explain the reasoning used.

Students in First Grade are expected to....
Use addition and subtraction within 20 to solve word problems by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Add and subtract within 20. Use strategies such as counting on; making ten; decomposing a number leading to a ten; using the relationship between addition and subtraction and creating equivalent but easier or known sums.
Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20.
Students in First Grade are expected to....
Apply properties of operations as strategies to add and subtract (commutative property of addition; associative property of addition).
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
Students in First Grade are expected to....
Compose two and three- dimensional shapes and distinguish between attributes.
Build and draw shapes to possess attributes.
Students in First Grade are expected to....
Partition circles and rectangles into two and four equal shares.
Understand that decomposing into more equal shares creates smaller shares.
Students in First Grade are expected to....
Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Use standard and non-standard units of measure to express the length of an objects a whole number of length units.
Understand that the length measurement of an object is the number of same-size length units.
Understand that the length measurement of an object is the number of same-size length units.
Students in First Grade are expected to....
Tell and write time in hours and half hours using analog and digital clocks.
