Addition and Subtraction
Tell students to create a web about everything they know about math and how they can relate.
Students will work together in order to create a math web. They will think of things in the real world that relate to math.
2 Guided Practice
Teacher will go over adding and subtracting and give a few examples of addition and subtraction. Then the teacher will show them the app "Numbers and counting adventures" and they will try the app on their own.
Students will learn about addition and subtraction and then they will explore the app "Numbers and counting adventures."
3 Independent Practice
The teacher will introduce the next app and show the students how to use the app. Each student will work on the app independently.
The students will focus on subtraction independently with the app "math- decimals subtraction."
Teacher will bring the class together and ask the students what they learned, what they had fun with, what they had difficulties with.
The students will briefly discuss addition and subtraction and the apps they used for the lesson.
Key Standards Supported
|HSA.CED: Create Equations That Describe Numbers Or Relationships|
|HSA.CED.1||Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.|
|HSA.CED.2||Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.|
|HSA.CED.3||Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or non- viable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods.|
|HSA.CED.4||Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm’s law V = IR to highlight resistance R.|
