Counting and Cardinality

Count to 100 by ones and tens Represent and write numbers for 0 - 20 Count to tell the number of objects

• • •

• Compare numbers; greater than, less than, equal • Compare written numerals between 1 and 10

Operations and Algebraic Thinking

• Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from o Represent addition and subtraction o Solve addition and subtraction word problems within 10 o Decompose numbers less than or equal to 10 o For any number from 1 to 9, find the number that makes 10 when add to the given number o Fluently add and subtract within 5 • • Work with numbers 11-19 to gain foundation for place value o Compose and decompose numbers • •

Represent and solve problems involving addition and subtraction within 20 • Understand and apply properties of operations and the relationship between addition and subtraction o Understand subtraction as an unknown-addend problem • Relate addition and subtraction with 20 to counting • Add and subtract within 20 • Understand the meaning of the equal sign • Work with addition and subtraction equations • Compare two-digit numbers based on tens and ones • Use place value understanding and properties of operations to add and subtract o Add within 100 o Mentally find 10 more or 10 less with two-digit numbers o Subtract multiples of 10 in the range of 10 -90 from multiples of 10 in the range of 10-90 Measure lengths indirectly and by iterating lengths units • Tell and write time in hours and half-hours using analog and digital clocks • Organize, represent and interpret data up to three categories • Identify and compare the values of pennies, nickels, dimes and quarters Reason with shapes and their attributes o Distinguish between defining vs. non-defining attributes o Compose two-dimensional or three-dimensional shapes to compose and create shapes o Partition circles and rectangles into two and four equal shares Read, write, count and represent to 120 Understand place value of tens and ones

Numbers and Operations in Base Ten

Measurement and Data

• Describe and compare measureable attributes such as length and weight • Directly compare two objects with the same measurable attribute in common and describe the difference • Classify objects and count the numbers of objects in categories • • Identify, name and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres) • Identify shapes as two-dimensional or three-dimensional • Analyze, compare, create and compose shapes •
