Use addition and subtraction within 100 to solve one- and two-step
word problems involving situations of adding to, taking from, putting
together, taking apart, and comparing, with unknowns in all positions,
e.g., by using drawings and equations with a symbol for the unknown
number to represent the problem.

| Word Problems Galore! Differentiated Math Centers | This lesson contains center rotations based on student ability of below, on or above grade level, including differentiated materials for each. It includes a diagnostic assessment and an exit slip to ensure each student's needs are being met. Students will work directly with the teacher for explicit instruction, they will work in a writing center to create a plan for solving word problems and in an independent center applying the skills. |
| Table Top Problem | The Junior League needs the students' help to determine which table rental company to use for their Charity Auction. With a tight budget, limited time, and a mistake in the order, students must create a procedure for determining the best rental company, write an explanation about their procedure, and present their recommendations to the class. Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations.

| Words and Subtraction | In this lesson, students will build on their earlier work of representing and solving situational problems (result unknown, change unknown, start unknown). Students will use related equations or drawings. |
| Let's Do Some Solving | In this lesson students will solve one-step addition word problems using base ten blocks, hundred charts, drawings, or strategies based on place value and/or the relationship between addition and subtraction. |
| Roll and Add Two Digit Numbers | In this lesson students will use two dice to roll and add two-digit numbers. Students will also use their numbers to create and solve one-step addition word problems. |
| Are Your Numbers Equal to My Numbers? | This is a lesson that reinforces the meaning of the equal sign while students determine the unknown whole number in an addition equation. |
| Amazing Animal Athletes (Addition and Subtraction Story Problems) | In this lesson, students will be able to solve one and two step word problems using addition and subtraction to compare human and animal athletic abilities. This lesson focuses on identifying the information given, comparing numbers, and identifying the missing information needed to solve the word problem using either addition or subtraction. |
| Officer Buckle Can Help Our Schools! | After reading, Officer Buckle and Gloria the students will be given a problem showing different ways safety problems have been solved at area schools. Through ranking, they will have to determine which manner was the most effective.

| Ten-Hut! Part-2 (Subtraction) | This fun, kinesthetic lesson allows students to gain insight into how to use place value when subtracting a one-digit number from a two-digit number. The focus is on students using their bodies, as well as math manipulatives, to solve subtraction problems within 100 that do not require regrouping. |
| Math Doctor: Which Operation? | In this lesson, students will be learning interpretation strategies for addition and subtraction word problems, such as circling numbers, underlining key words, choosing operations, and showing their work to solve word problems. |
| Success with Story Problems - Addition/Subtraction | In this lesson, students will solve one and two-step real-world problems using a variety of problem-solving strategies. |
