1. Estimate and explain your thinking when dividing very large numbers to determine an approximate percent.
2. Use scientific notation to solve problems with really big numbers or really small numbers and be able to convert those numbers into other units that provide a better understanding of what those numbers represent.
3. Be able to provide a pictorial representation of fractions, whether using a discrete whole or a continuous whole.
4. Write a decimal number as a fraction in the form: i.e 2.25 = 225/100 = 9/4, or 2.2525252525... = 223/99
5. Demonstrate understanding of decimal numbers by finding numbers that would be between consecutive decimal numbers. i.e. what decimal numbers are between 0.2 and 0.3
6. Use approximation to find an estimate of the answer when doing addition, subtraction, multiplication or division involving mixed numbers.
7. Find a fraction between fractions with unlike denominators without converting to decimal numbers or using common denominators. This means understanding how “neighbor numbers” work.
