2nd Grade, Math, Math Skills Review

Identifying Even and Odd Numbers takes practice!

For older students and adults, it’s really easy to identify whether a number is even or odd, but for 1st – 3rd graders, it can require practice!

Yes, we can tell students that if a number ‘ends in 0, 2, 4, 6, or 8’ it is an even number. We can also tell them that all other numbers (ending in 1, 3, 5, 7, or 9) are odd numbers. We can also display posters to help them such as Math Posters | Even – Odd Numbers but students still require practice!

That’s why My Teaching Library has created….Even and Odd Numbers

This resource will give students the practice they need to identify even and odd numbers! It includes 18 worksheets that progressively include higher numbers to really help students solidify their understanding.

Includes:

  • – 4 worksheets (#’s to 20) w/ pictures: Students are to count and write how many, then create pairs (to determine if the number is even or odd) and then will circle even or odd.
  • – 3 worksheets (#’s to 20) for students to identify odd numbers (given a sets of  6 numbers, they will circle every odd number)
  • – 3 worksheets (#’s to 20) for students to identify even numbers (given a sets of  6 numbers, they will circle every even number)
  • – 2 worksheets (#’s to 20) for students to identify both even and odd numbers (given a sets of  4 numbers, they will circle every even or odd number based on instructions given)
  • – 4 worksheets (#’s to 50) for students to identify both even and odd numbers (given a sets of  4 numbers, they will circle every even or odd number based on instructions given)
  • – 2 worksheets (#’s to 120) for students to identify both even and odd numbers (given a sets of  3 numbers, they will circle every even or odd number based on instructions given)
  • – Answer Keys

Although 2nd grade skills require that students can identify even and odd numbers through 20, it is easy for them to go beyond twenty using this resource and the concepts they learn! Perfect to pair with Math Posters | Even – Odd Numbers

Addition and Subtraction with Blocks | Sums – Minuends to 20

In 1st grade and again at the beginning of the 2nd grades, students are expected to add and subtract with sum and minuends to 20. To help students gain insightful understanding (and not just facts), the use of blocks to help them visualize the addition and subtraction problems is very beneficial. My Teaching Library has a 10 page pdf (download, print and use) workbook to help students gain the practice and understanding they need for this skill…

This workbook includes:

  • 5 addition worksheets each including 12 problems to solve with visual blocks plus one addition problem for students to solve without blocks. For this final problem, students are asked to draw blocks to show their understanding.
  • 5 subtraction worksheets each including 12 problems to solve with visual blocks plus one subtraction problem where students are to label the minuend and the subtrahend.
  • Answer keys

4th Grade Math – Adding and Subtracting Fractions with Like Denominators

In 4th grade, students should learn to add and subtract fractions. The first step is to teach students to add and subtract fractions with ‘like’ denominators.  

Here are examples of adding fractions with like denominators:

Here are examples of subtracting fractions with like denominators:

Students can easily begin with like denominator fractions because it only requires that they add or subtract the numerators.

All the above examples are proper fractions and the easiest for students to work with.

However, there are three types of fractions…

Proper Fractions:
The numerator is greater than (or equal to) the denominator
Improper Fractions:
The numerator is greater than (or equal to) the denominator
Mixed Fractions:
A whole number and proper fraction together –

Fraction Types: Proper, Improper, Mixed

If students are adding and subtracting improper fractions, adding and subtracting is still straightforward as long as all fractions have like denominators. However, what should a student do when presented with mixed fractions?

First, each mixed fraction should be changed into an improper fraction. To convert a mixed fraction to an improper fraction, follow these steps:

  • Multiply the whole number part by the fraction’s denominator.
  • Add that to the numerator
  • Then write the result on top of the denominator.

Once all mixed fractions in an addition or subtraction problem are converted and all denominators are the same, then addition and subtraction can easily take place by adding or subtracting the numerators while the denominators stay the same!

To help students master adding and subtracting fractions with like denominators, My Teaching Library has developed these products…

Each of these downloadable, printable, ready to use workbooks include 10 worksheets. Each worksheet includes 10 problems. These workbooks also include answer keys so they are truly ready to print and go!


My Teaching Library has many additional fraction related resources! Here is a sample:
