Standards with the same topic and subject but for other grades
Make sense of quantities and their relationships in problem situations.
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
Reason quantitatively to recognize that a number is a multiple of each of its factors.
Progress from thinking about numbers as the result of the process of counting to abstractly thinking about numbers as mental objects of their own-especially the quantity 10.
Abstract comparisons between lengths using statements like 𝐴 > 𝐵.
Make reasoned arguments about the relative sizes of groups, such as by matching objects of two groups and seeing which has extra objects, or by counting the objects in each group and seeing which has the number further in the counting sequence.
Explain the equivalence of fractions.
Construct viable arguments about the addition and subtraction of fractions with reasoning rooted in the need for like-sized parts.
Defend calculations of area using multiplication and by tiling the area with square units and comparing the results.
Analyze and measure the size of angles in real-world and mathematical problems.
