Giggle Facts

50 Math Games and Math Worksheets for Third Graders!

The Giggle Facts Math Program helps 3rd Grade students master their Addition and Subtraction Facts, and helps kids have an easier time learning many of the other Grade 3 math concepts described on this page that they will encounter in Third Grade.

You will notice that many math concepts and math skills repeat over the Kindergarten, 1st Grade, Second Grade and 3rd Grade levels.  This is due to the fact that math concepts build on each other grade by grade.

3rd Grade Math Facts Are So Important...Learn Why

Math Facts: Addition and Subtraction


Adding and Subtracting Larger Numbers


Giggle Facts
is Great for
Third Graders!


Addition and Subtraction Math Facts will be reviewed in Third Grade.  Students will be expected to have a very good understanding of their Addition and Subtraction Facts at this stage. Addition and Subtraction Math Facts should be mastered by the start of the 3rd Grade.  Students should now know Math Fact Addition strategies such as “Doubles” (6+6 or 4+4), “Turnarounds” (2+7 = 7+2), “Near Doubles”, “Almost Doubles” or “Doubles Plus 1” (6+6+12, so 6+7= one more, or 13).


Third-Graders will continue to add and subtract larger numbers (ex: 2-digit numbers such as 456+192, or 725-581).  More than one Math method may be taught to solve these problems, including Mental Math.


Third Grade children need to spend time at home if they have not yet mastered their Math Facts.  Giggle Facts reinforces the math strategies taught in 3rd grade classrooms, and incorporates many others as well.

For some Grade 3 children, the transition to adding and subtracting larger numbers can be difficult.  Giggle Facts helps third grade students by giving them lots of fun practice with Math Facts, which eases the transition to working with larger numbers.


Math Facts - Multiplication and Division


Skip Counting and Using a Hundreds Board


Instant Recall of Math Facts is IMPERATIVE to Learning Higher-Level Math Concepts in 3rd Grade.  Read What Researchers Have to Say...


Students in Third Grade will continue working on their Multiplication and Division Facts.  They will continue to use vocabulary such as 'Product' (answer to a multiplication question), 'Quotient' (answer to a division question), Remainders, Fact Families, etc.  They will also be placing objects into equal groups, displaying numbers in arrays, and creating number stories.  This will extend into the memorization of the easier Multiplication Facts first, then to the more difficult Multiplication Facts.  They will also relate Multiplication to Division. 


Students in Third Grade will be expected to know how to skip count by 2s, 5s, and 10s (ex: 2,4, 6, 8, or 5, 10, 15, 20).  They may begin skip counting by other numbers such as 3,4,6,7,8 and 9 as preparation for Multiplication.   


The math knowledge and number sense that Third Grade students gain through the Giggle Facts math program will help them understand Multiplication and Division Fact Families.

Giggle Facts teaches Grade 3 children the relationship between numbers (Number Sense), which in turn helps with math concepts such as skip counting, greater than / less than, before / after, odd and even numbers, etc.




Place Value

Third Grade Math Fact Games

Third Graders will continue to count / add pennies, nickels, dimes, quarters, and dollar bills.  They will also continue working on the Math concept of making change.  Children who know their Addition and Subtraction Math Facts will, overall, have an easier time adding / counting money.  Students who have an understanding of Subtraction will have an easier time with making change. 


Students in Grade 3 will learn that each digit in larger numbers has a value, depending on its position in the number.  For example, in the number 52,478, the 5 is worth 5 “ten-thousands” (or 50,000), the 2 is worth 2 “thousands” (or 2,000), the 4 is worth 4 “hundreds” (or 400), the 7 is worth 7 “tens” (or 70), and the 8 is worth 8 “ones”, or simply 8. 


Children who have mastered their Addition and Subtraction Math Facts will have an easier time adding and counting money, and learning how to make change. Giggle Facts allows children to develop their number sense, which makes skip counting with money easier.

Giggle Facts teaches students to break down larger numbers into their smaller components (tens and ones) through two different math strategies.  There is an Addition strategy named  Teens”, and a Subtraction strategy named “More Teens” in the Giggle Facts math program that supports the math concept of Place Value. 




Telling Time

Third Graders will have many opportunities to measure in a variety of ways.  Grade Three students will continue measuring with standard units (ex: inches, feet, yards, and miles, or centimeters, decimeters, meters and kilometers), as well as temperature in Fahrenheit and Celsius using a thermometer. They will also measure to the nearest ‘part’ of a unit, such as measuring to the nearest ½ inch or ¼ inch, or to the nearest centimeter.


Telling time remains an important math skill that students will continue to review in Third Grade.  They will tell time to the hour, half-hour, quarter-hour, 5 minutes and 1 minute using both digital and analog clocks. They will also be expected to know different ways to express the time, such as half-past 3 and a quarter-to 9.  The Math Concept of elapsed time will be reviewed.


The keen number sense that Third Grade students will develop through the Giggle Facts math program will aid them in understanding the tricky math concept of telling time.

3rd Grade Math Fact Fun





Top 3 Reasons Many Teachers Recommend You Learn More About Giggle Facts!


Fractional parts of a whole will be investigated in 3rd Grade Math (ex: the child will see a circle, and will divide it into several equal parts like halves, thirds, fourths, sixths, etc.).  Fractions of a group will also be reviewed (ex: how to divide a class of 24 children into 6 equal groups).  Third Grade students will shade in parts of an object to show a specified fraction, and they will continue to investigate equivalent fractions.  Third-Graders will also learn about Improper Fractions and Mixed Fractions.   

GiggleFacts - the Answer to 3rd Grade Math Facts

An image that is symmetrical is something that has two sides that are identical.  One side could be seen as a “mirror image” of the other side.  3rd Grade students will have opportunities to look for symmetry in everyday objects, as well as create symmetrical patterns of their own.  They will determine whether certain objects or pictures display line symmetry, and the number of lines of symmetry in those objects or pictures.
