Learning how to check our work is essential to becoming strong math students! In this exercise, students will first solve the subtraction problems, then they'll practice checking their work by plugging the answers into an addition equation.
Word problems make for great assessment tools because they require a complete understanding of the math concepts. Use this assessment to evaluate your students' abilities to add and subtract three-digit numbers using mixed operation word problems.
This lesson helps students develop an ability to compare and contrast as they explore two strategies to solve three-digit addition problems. This EL Math lesson can be used alone or alongside Three-Digit Addition Strategies Review.
Let's see how those addition skills have blossomed over the course of the year! Use this quick math assessment to gauge your students' abilities to add three-digit numbers, both with and without regrouping.
Use this worksheet to continue practice with two addition strategies: expanded notation and standard algorithm. Students will be challenged to solve three-digit addition problems and then check their work using multiple methods.
Use this worksheet to practice two strategies for solving three-digit addition problems. Students will flex their math muscles as they use both the expanded notation and standard algorithm strategies to solve challenging math problems.
Plan ahead for when you'll be out of the classroom! Planning for a substitute in the classroom is no problem at all with this daily sub plan. Your substitute can keep your students learning in your absence by using this packet of lessons, worksheets, and activities.
After your students have mastered two digit addition, get them going on three digit addition by incorporating worksheets that not only keep learning fun but help keep everything in order. It’s easy for students to get confused when working on addition problems that incorporate multiple digits, but these worksheets will lay out everything clearly and keep everything organized when teaching three digit addition.
Multi-digit addition is the first thing early learners will do that will break out of something they can do on their fingers. This will be their opportunity to use mental math and the addition within 10 that they’ve memorized in order to solve complicated problems.
There are multiple ways of solving three digit addition problems. One of the foundational concepts behind our learning system is to approach problems from different directions. This increases understanding and number sense. Practicing these methods using the resources provided by Education.com above may help students gain proficiency in three digit addition.
If your student is attempting three digit addition, they should already have a good grasp of addition up to 10. The break apart method uses this foundation by breaking the numbers into whole hundreds, tens, and ones, then adding those individually. Each of these individual problems can be done as a single digit problem, simply adding the zeros on afterwards. The sums are then added together to get the final sum of the original problem.
Using a number line is similar to the break apart method but also helps the student visually understand how the numbers are increasing. In order to use the number line method, students would draw a number line and write one of the two addends at the starting point of the number line. Then they will jump forward once for each hundred, writing the new number on the number line. This process is repeated with the tens and ones until the final sum is reached.
