Place Value to Thousands: Find the Value of an Unknown Number
Hello and welcome to the final handout in our Place Value with Addition and Subtraction unit. We couldn't be happier to share it with you!
This time we explore finding the value of an unknown number in both addition and subtraction number sentences. In the mini-lesson we teach finding the sum, the first addend, the second addend, the difference, the subtrahend, and the minuend. Awesome, right? We sure think so. Folks, we've created 3 whole pages of practice! Don't let this handout pass you by :)

. It’s pretty rad.
Now, let’s take a closer look at how this handout is structured.
Here's what we provide:
* Mini-Lesson: Learn the Skill
-Skill is laid out in an easily digestible format with vocabulary, definitions, diagrams and an example problem. Students have this tool at their fingertips while completing the assignment.
* Use What You Know: Apply the Skill
-Offers immediate reinforcement of the skill. Questions approach problems from more than one angle to ensure full understanding.
* Show What You Know: Word Problems
-This section helps students practice determining what a question is asking them, as well as how to recognize and use key words.
* Write What You Know: Writing in Math
-This section helps students practice expressing their reasoning strategies in complete sentences.
* Prove What You Know: Test Prep
-Students can never be TOO ready for EOGs, EOCs, and other standardized tests, so here they practice good test-taking strategies with multiple choice questions.
* Spiral Review
-Kids' brains are like sponges, but knowledge can leak back out if they don't re-soak, so to speak. This review dusts the cobwebs off of earlier units.
* Answer Key
-Time is money (or rest, or quality time with your family, or really whatever you want to spend it doing), so we always include answer keys for the teacher-on-the-go!
* Print in color for best results
* Consider printing front and back for green points
* Consider splitting up the longer handouts (more than 2 pages) across multiple days (i.e. odd/even)
* Continue shopping at the 88Brains store ;)
* Keep being awesome
