﻿ Grade 1 Word Problems(examples, solutions, songs, videos, games, activities) Related Topics:

Examples, solution, videos, and songs to help Kindergarten kids learn how to use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

• I can make sense of quantity and be able to compare numbers
• I can use flexible thinking strategies to develop the understanding of the traditional algorithms and their processes
• I can solve a variety of addition and subtraction word problems
• I can use _ or ? to represent an unknown in an equation
• I can model addition and subtraction word problems using objects, drawings, and equations with unknown numbers in different positions.
• I can add three whole numbers whose sum is less than or equal to 20.
• I can solve word problems with three whole numbers using objects, drawings, and equations.
• I can add numbers in any order and be able to identify the most efficient way to solve the problem

Result Unknown
Two bunnies sat on the grass. Three more bunnies hopped there.
How many bunnies are on the grass now?
2 + 3 = ?

Change Unknown
Two bunnies were sitting on the grass. Some more bunnies hopped there. Then there were five bunnies. How many bunnies hopped over to the first?
2 + ? = 5

Start Unknown
Some bunnies were sitting on the grass. Three more bunnies hopped there. Then there were five bunnies. How many bunnies were on the grass before?
? + 3 = 5

Subtraction Examples:

Result Unknown
Five apples were on the table. I ate two apples.
How many apples are on the table now?
5 – 2 = ?

Change Unknown
Five apples were on the table. I ate some apples. Then there were three apples.
How many apples did I eat?
5 – ? = 3

Start Unknown
Some apples were on the table. I ate two apples. Then there were three apples.
How many apples were on the table before?
? – 2 = 3

Word Problems. Addition with pictures (up to sum 20)
