Standards and E-Skills
Standard 1:
(Number Sense) Students develop number sense and use numbers and number
relationships in problem solving situations and communicate the reasoning in
solving these problems.
Locate
positive fraction on a number line. Represent and use fractions in a variety
of models and then write the equivalencies for each model. Convert positive
rational numbers into equivalent fractions, decimals and percents.
Demonstrate
understanding of equivalent representations of fractions.
Standard 6: (Computation) Students link concepts and procedures as they
develop and use computational techniques, including estimation, mental
arithmetic, paper-and-pencil, calculators, and computers, in problem-solving
situations and communicate the reasoning involved in solving these
problems.
Add and subtract fractions in problem-solving situations. Apply
computational strategies including traditional algorithms for adding and
subtracting fractions.
Apply appropriate computational methods to solve a problem.
Apply computational
skills to find reasonable answers. Determine what information is necessary
in a problem-solving situation.
