LH-stage+1

1.Write and interpret numerical expressions.
 * Established Goals:**
 * State Standards**:

 1. Use place value understanding to round whole numbers to the nearest 10 or 100.  * 2. Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.  . * 5. Fluently multiply multi-digit whole numbers using the standard algorithm.
 * 6. Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
 * 7. Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

Students will understand that: · Mathematics and the ability to compute numbers allows us to make technological advances and help improve our society and the environment. · In order to record and learn from data we must be able to use and compute integers and create and interpret coordinate planes.
 * Understandings**:

**Essential Questions/Big idea**
 * What are some negative consequences that could arise in the environment if we didn't have mathematics to help us study and learn about the environment?
 * How would your life be different if we didn't have a number and monetary system?
 * How will being able to do simple numerical operations benefit us in life?
