Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Big Idea:Which one of these is not like the other?! Students apply their understanding of 3 addend equations to decide which number sentence in a group of 4 is false. First person to find the false number sentence wins!
The Number 10 and the Addition and Subtraction Concept
Big Idea:Understanding the meaning of the equal sign and finding missing addends to make equations true are the big ideas today. Students engage in conversation and activities to discuss their understanding and thinking.
Big Idea:ADDITION...it is one of the most important concepts we need our first graders to develop in math. This lesson will begin building the foundation for strong skills in addition through the use of rich vocabulary.
Big Idea:It's a Graph Party and you're invited! Today the students will be involved in creating three different types of graphs and then be asked to answer questions about each representations data set.
