  1. Learning Objective We will solve1 addition word problems. What are we going to learn? What does solve mean? Solve means ______________. CFU Activate Prior Knowledge The equal sign (=) means the same. = Add. Write and the answer. = 3 + 2 5 Students, you already know how to add and use the equal sign. Now, we will solve addition word problems. Make Connection 4 + 5 1 find the answer Vocabulary

  2. Concept Development 1 • Addition means to put together. • An equation uses an equal sign to say two amounts are the same. • An equation can represent2 an addition word problem. • In a word problem, some and few are clue words that show unknown amounts. CFU 1 Which equation represents the following: There are five balls on the floor. Four more balls were put there. Some balls are now on the floor. In your own words, what is an equation? An equation is ________. Addition Word Problem Go to Skill Dev 1 Three birds were on the branch. Two more birds flew there. Some birds are now on the branch.
