Addition Word Problems Mastery

What type of problems will be discussed in Lesson 11?

• Division problems

• Subtraction problems

• Addition word problems with missing add-ins

• Multiplication problems

How are math word problems similar to movies and books?

• They are always about heroes

• They are set in different places

• They have recurring plot lines

• They have different characters

What is a 'some and some more' problem?

• A problem where you are given some items and then some more items are added

• A problem where you divide two numbers

• A problem where you multiply two numbers

• A problem where you subtract two numbers

In the first example, how many marbles did Walter have initially?

• 5

• 17

• 8

• 9

What is the missing number in the equation 8 + m = 17?

• 7

• 8

• 10

• 9

How can you solve for the missing number in an addition problem?

• By adding the total to the known addend

• By subtracting the known addend from the total

• By multiplying the total by the known addend

• By dividing the total by the known addend

In the second example, how many apples did Jamie pick initially?

• 5

• 7

• 9

• 12

What is the equation for the second example involving apples?

• 12 - a = 5

• a + 5 = 12

• a - 5 = 12

• 5 + 12 = a

How can you find the initial number of apples Jamie picked?

• By adding 5 to 12

• By subtracting 5 from 12

• By multiplying 5 by 12

• By dividing 12 by 5

What is the key to solving 'some and some more' problems?

• Knowing the total and one of the addends

• Knowing the missing addend only

• Knowing both addends

• Knowing the total only
