Flexibility and fluidity with addition is an important part of the first grade math curriculum, but it takes lots of practice to gain confidence with this skill. This lesson in addition offers guided practice which aims to increase mental math and fluency with addition. When your child finishes this lesson, you can continue the addition practice by downloading and printing the accompanying addition worksheets.
First graders' fluidity with comparing numbers is an important building block for the higher-level math concepts to come in the later grades. You can give first graders a leg up with this lesson, featuring guided instruction and practice problems in comparing numbers. Once kids get through this lesson, you can download and print the suggested comparing numbers worksheets in order to provide even more opprotunities for practice.
Understanding the value of a number has never been more inviting. This series of worksheets will give your second grader the opportunity to count, read and compare numbers.
Our two-digit addition activities keep learning engaging and productive for even the youngest of students. From worksheet handouts to class-wide games, add it all up and the result is confident students who are working on mastering the foundational skills of mathematics. For students who need review, head over to our addition within 10 resources.
After early learners master counting to ten and addition within ten, it will be time to challenge them with two digit addition. Two digit addition will likely be the first time students attempt a math problem that will require mental math, as they won’t have enough fingers to count them.
One of the most important steps to acquiring number sense is to approach problems using different strategies. Some of the resources provided by Eduction.com may give students an opportunity to practice each of these methods.
Vertical Addition
The vertical addition method requires the student write the two addends, one on top of the other, with a vinculum underneath. The vinculum is the horizontal bar that will separate the addends from the sums. The first step of the vertical addition method is to add together the numbers in the ones column and write the sum under the vinculum. Now the digits in the tens columns are added. Remember that numbers in the tens column represent multiples of ten. Write this sum under the previous sum. Add the two sums together to get the greater sum.
Algorithm or Regroup Method
The algorithm method has students, once again, write the two addends, one over the other, on top of the vinculum. First the ones are added together. If the sum is greater than 10, the 10 is moved over the tens column and only the ones digit is written under the vinculum. Now the tens are added together, including the regrouped ten. This sum is written next to the previous sum. Read from left to right, this is the final sum of the problem.
