➥ 1.OA.3 – Apply properties of operations as strategies to add and subtract

➥ 1.OA.4 – Understand subtraction as an unknown-addend problem

➥ 1.OA.5 – Relate counting to addition and subtraction

➥ 1.OA.6 – Add and subtract within 20, demonstrating fluency for addition and subtraction within 10

➥ 1.OA.8 – Determine the unknown whole number in an addition or subtraction equation

WHAT ARE POWER PROBLEMS?™

PURPOSEFUL - These problems are meant to keep students focused, while strengthening initiative and perseverance.

OPPORTUNITIES - These prompts can be used in a variety of ways. POWER Problems can be used to introduce a lesson, spiral review, or as formative assessments.

WITH

ENGAGEMENT - Problems are real world applicable and designed to hook students with interest and presentation. Complexity of problems promotes problem solving skills.

RIGOR - Tasks are specifically designed to challenge students and assess conceptual understanding of curriculum versus procedural understanding. Students will need to apply more than just a “formula.”

WHY USE POWER PROBLEMS?™

BUILD STAMINA WITHIN YOUR STUDENTS!

POWER Problems are designed to challenge your students with their open ended presentation. Majority of problems that come from textbooks and workbooks assess procedural understanding of curriculum. Some textbooks even provide step by step instructions where the textbook is thinking for the students and taking away that “productive struggle” for children. When we rob students of that event, we rob them of their ability to reason, problem solve, and see beyond a standard algorithm. POWER Problems are meant to show students that there are different ways to answer one question in math. With these tasks students take ownership and are part of the problem solving process versus filling in blanks in a textbook.

HOW TO USE POWER PROBLEMS™:

TO INTRODUCE A LESSON - POWER Problems can be used to introduce a new skill. In this case your students will experience a “productive struggle.” Their problem solving skills and prior knowledge will kick in. Often times most of my students will have the incorrect answer or no answer at all. I then have someone explain their method/reasoning and allow my students to critique their peer’s answer. This makes for great accountable talk discussions. If I see that most students do not have an answer I will assist the class in getting to a specific point and then allow them to finish independently.

SPIRAL REVIEW - Avoid your students forgetting standards, by using POWER Problems to spiral review previously taught lessons.

FORMATIVE ASSESSMENTS - You can use these problems to assess mastery and levels of understanding.

### Standards

to see state-specific standards (only available in the US).
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
