Represent addition and subtraction with objects, fingers, mental images, drawings (drawings need not show details, but should show the mathematics in the problem), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

Big Idea:
When introducing subtraction, students can become easily overwhelmed with numbers and symbols. In this lesson, students will learn using cubes to solve subtraction word problems related to under the sea.

Big Idea:
In order to share the answer to a word problem, it is common practice to write a numeral as the solution to the problem. In this lesson, the students will keep practicing using manipulatives to solve subtraction word problems but will also write the answe

Big Idea:
When introducing subtraction, students can become easily overwhelmed with numbers and symbols. In this lesson, students will learn using cubes to solve subtraction word problems about space.

Big Idea:
We have 10 fingers, so when learning to subtract starting with a number less than 10 or equal to 10, students can use their fingers to help them. Manipulatives and drawings are helpful too!

Big Idea:
Students will review the meaning of the equal sign. Students will practice putting the symbols in the correct place in subtraction equations.

Big Idea:
At the end of the year, a lot is going on in our classroom. We continue our center routine for additional practice and to allow for end of the year testing to be completed.

Big Idea:
After reading If You Were a Minus Sign, students create their own number stories, by representing subtraction using pictures and possibly equations.

Big Idea:
After reading If You Were a Plus Sign, students create their own number stories by representing addition using pictures and possibly equations.
