Grade 1 math, age 6 to 7

In Grade 1, students develop fluency with addition and subtraction within 10 and strategies for adding and subtracting within 20. They build an understanding of whole-number relationships and base-ten place value, grouping numbers into tens and ones up to 100. Students also measure lengths indirectly, tell time to the hour and half hour, and partition two-dimensional shapes into halves and quarters.
