     - Why are exponents solved before addition?
     - Students can see why adding before solving the exponents changes the meaning of the problem and the answer 
     - Ex. 8 + 3 x 5  = 23 
- PEMDAS or BODMAS/BEDMAS/BIDMAS
     - parentheses/bracket, 
     - exponents/order/indices
     - Can lead students to think addition is done before subtraction and multiplication is done before division 
     - Visuals can be more beneficial ]]> 2017-03-23 17:33:31 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162218177 etjones3 https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162222990 - Scientific notation means a number is changed to be the product of a number greater than or equal to 1 and less than 10 multiplied by a power of 10.

Example: In 2014, the population of the world was 7, 171,919,206. This number can be expressed in a number of ways using scientific notation:       
        - 7,172 million
        - 7.2 x 10^9 
        - Nearly 7 billion]]> 2017-03-23 17:45:55 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162222990 gstrunk https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162224419 - Positive/negative whole numbers and zero
- Context for positive and negative numbers: 
       - Temperature, altitude, golf, money, timelines, football yardage  
       - Absolute value is the distance from zero 
       - The negative sign (minus sign) can be confusing to students
- Effective models for teaching Positive/Negative numbers, should be chosen based on context:
       - Counters
       - Number Lines 
- Addition and subtraction: ask questions such as Where did you start? How far did you go? Where are you now? 
- Multiplication and division:  3 x -4 is the same thing as positive 3 sets of -4, -2 x -3 is the same thing as negative 2 sets of -3 less than zero (make zero pairs then take away two pairs of -3 and you are left with positive 6)]]> 2017-03-23 17:49:30 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162224419 apmorell https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162225045 - A whole number exponent is repeated multiplication of a number times itself.
- Exponents are first introduced to students in 5th grade relating to powers of 10 and place value.
- A common confusion for students is whether to add or multiply the exponents.
- Teachers can connect what students already know with area to exponents through a pen picture chart.]]> 2017-03-23 17:51:13 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162225045 ctuzzoli https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162225974 Organization of the real numbers.]]> 2017-03-23 17:53:32 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162225974 ctuzzoli https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162230406 Order of Operations]]> 2017-03-23 18:04:54 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162230406 ctuzzoli https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162230614 Student example record possible areas for making a square pen.]]> 2017-03-23 18:05:33 UTC https://padlet.com/cassiidyraae/wqbq23cb3o2m/wish/162230614
