math 5 Updates
Fifth graders continue practice of order of operations, expressions and equations. They are also working with coordinate grids to determine how to plot points. We look forward to watching the final four on March 31st so we can complete our March Madness Project. Lastly, this year 5th grade will complete the clock activity and a walk-a-thon project.

Learners will review order of operations (PEMDAS) and work to understand expressions.
For example, "4 times the sum of 6 and 2" or "3 times the sum of an unknown number c and 15" An Algebraic Expression.- An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide). We also reviewed variables. Variable- A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. Lastly, we are finishing up our March Madness project packets and continuously reviewing how to change fractions to decimals and percents. Fifth graders are completing March Madness Brackets. We will review the order of operations and go back to work on converting fractions to decimals and percentages. This project gives us the perfect opportunity to investigate the relationships between percents, decimals and fractions. We will also look into expressions.

In the meantime, fifth graders are learning about order of operations. We are using PEMDAS to help us remember order of operation. P = parenthesis E = exponents M = multiply D = divide A = add S = subtract. We use order of operations when solving longer equations. For example, 10 + 3(2 + 6) = 3 x 8 = 24 plus 10
