## Number and Operations-Fractions

I Can Use Fractions to Help Me Understand Math

* I can explain (and show models for) why multiplying  a numerator and a denominator by the same number does not change the value of a fraction.  4.NF.1

* I can compare two fractions with different numerators and different denominators by creating  common denominators or numerators or by comparing them to a benchmark fraction like one-half.  4.NF.2

*I can recognize  that comparisons of fractions are valid only when the two fractions refer to the same whole.  4.NF.2

*I can compare fractions using symbols and justify the comparison by using models.  4.NF.2

*I can understand that improper fractions have a greater numerator than denominator.  4.NF.3

*I can understand addition and subtraction of fractions as joining  and separating parts referring to the same whole.   4.NF.3

*I can decompose a fraction into  a sum of fractions with the same denominator.  4.NF.3

*I can add and subtract mixed numbers with like denominators.    4.NF.3

*I can solve word problems involving  addition and subtraction of fractions with like denominators.  4.NF.3

*I can multiply a fraction by a whole number.  4.NF.4

*I can solve word problems involving multiplication  of a fraction by a whole number.  4.NF.4

*I can show a fraction with a denominator of 10 as an equivalent  fraction with a denominator of 100 in order to add the two fractions.  4.NF.5

*I can use decimals to show fractions with denominators of 10 and 100.  4.NF.6

*I can compare two decimals to hundredths by reasoning about their size.  4.NF.7
