About the Math
Students have used algebraic expressions to generate answers when given values for the variable. This understanding is now expanded to equations where the value of the variable is unknown but the outcome is known. For example, in the expression, x + 4, any value can be substituted for the x to generate a numerical answer; however, in the equation x + 4 = 6, there is only one value that can be used to get a 6. Problems should be in context when possible and use only one variable. Students write equations from real-world problems and then use inverse operations to solve one-step equations based on real world situations. Equations may include fractions and decimals with non-negative solutions. Beginning experiences in solving equations require students to understand the meaning of the equation and the solution in the context of the problem. Essential vocabulary for this standard includes: equations, profit, and exceed.

Explain how to solve an equation using physical models (algebra tiles).
These tasks can be used with small group or whole group instruction.
George paid a total of $15.25 for a pizza with some toppings. The pizza without toppings cost $11.50. Write an equation to show the cost of toppings, t.
Chase now has a total of $3.25 after his friend gave him $1.12. How much money did Chase begin with before his friend gave him money. Write an equation to show how you solved the problem.
Connor has a cell phone plan where he pays $55 for unlimited talk time minutes and a total of 30 text messages. Last month Connor sent a total of 48 text messages, so he needs to pay $0.08 for every text message sent over the 30 allotted. Write an equation to show what Connor will need to pay the phone company. Now solve.
A student company charges a $5 flat fee plus $3 per window to wash windows. How much more would someone have to pay to have 35 washed than 24 windows? Write equations to support your answer. Could someone pay $87 to have their windows washed? Justify your answer.
Gloria raised $90 for a charity. This is ⅔ the amount that Fiona raised for the charity. Write and solve an equation to determine the amount, d, in dollars that Fiona raised for the charity.
SLIDE-BASED TASKS
These links are HCPSS created instructional tasks. These tasks are provided in Google slides.These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first(often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
CC - Indicates colleague created instructional tasks. These tasks are provided in Google slides. When selected, a copy of the file is added to your drive for classroom use.
These resource sheets can be used for independent practice, homework, or assessment. They are intended to reinforce procedures and concepts. They should not be used as a source of direct instruction or whole-group practice.
