Greater or Less ThanThis post is the fourth in a series on encouraging intuitive math skills in preschool children.  If you would like to see the first post (Number Awareness and Recognition, 1-to-1 Correspondence, and Subitizing), you can view it here.  Activities for 5 and 10 Frames can be printed here, and suggestions for introducing Part Part Whole can be seen here.

There are 6 important number concepts that preschoolers need to have opportunities to explore through play in order to develop good math intuition skills.  This numbers post (Part Four} will concentrate on playing and learning with the concepts of:  More Than, Less Than, and Equal To.

6 Important Number Concepts for Preschool

More Than, Less Than, or Equal To

As Early Childhood Educators, we receive children from different backgrounds and with different skill sets.  This math series seeks to build upon skills by introducing important concepts that young children should be offered opportunities to play with and explore.  Please take a moment to browse the other posts offered in the Intuitive Math series (linked above) for ways to introduce number concepts to preschoolers.

Mr. Munching Mouth Collage


As young children gain confidence in subitizing (the ability to intuitively know HOW MANY objects are in a small group) and become familiar with basic numbers and counting, we can begin to introduce the concepts of:  Greater Than, Less Than, and Equal To.   We use a cross-curriculum concept for introducing our kids to each of the symbols.  For early literacy, our kids still LOVE the Letter People.  We have the all of the original letter people in our classroom; “Mr. Munching Mouth” is a name that is very familiar to our kids.

Invite your kids to make the hand signs (as pictured above) to help them visualize the symbols for Greater Than, Less Than, or Equal To.  Explain to the children that Mr. Munching Mouth always wants to MUNCH on the bigger numbers; his mouth always opens toward the number that is larger.  When the numbers are the SAME, Mr. Munching Mouth closes his mouth to form the EQUAL sign.  Invite the children to practice with their hands to make a “munching mouth” that is Greater Than, Less Than, or Equal To.

NUMBER_LINEMake a basic number line for the children.  Begin with the numbers 1-5 and invite the children to practice MUNCHING on numbers that are BIGGER than number one.  Which way will Mr. Munching Mouth open?  As the children gain confidence, randomly pick a number between 1 and 5 and ask the children to form the appropriate hand sign.  For example:  Is the number 3 GREATER THAN or LESS THAN the number 5.  Remind the children that Mr. Munching Mouth always wants to MUNCH on the LARGER number and opens his mouth in that direction.  If the numbers are the SAME (equal to), Mr. Munching Mouth closes his mouth slightly to make the = symbol.

Great Than_Less Than_PracticeMr. Munching Mouth Center or Tray Activity – Mr. Munching Mouth                                                                                                   Mr. Munching Mouth Numbers

Materials needed:  One Mr. Munching Mouth file (linked above), any counters or manipulatives (suggestions:  Unifix cubes, pompoms, blocks, large “wiggly craft eyes”, shells, stones, marshmallows, or bingo chips), and one copy of Mr. Munching Mouth Numbers (linked above).  NOTE:  please be aware of young children who still put objects in their mouth.  Small manipulatives are a choking hazard and larger items for counting should be used.

Prior to the activity:  Print the Munching Mouths and Numbers Cards from the files above, laminate for durability, and cut out.  Note:  the second page of the numbers file is left intentionally blank for use with any numbers, number words, tally marks, or dots to vary the math activity.

On a tray or a table, make two piles of number cards, any manipulatives desired, and all 3 of the munching mouth cards.

The children should pick two number cards and decide which munching mouth symbol represents the relationship between the two numbers:  Greater Than, Less Than, or Equal To.

As the children gain confidence, add larger numbers for the children to practice with.

The following games are also fun for preschoolers to explore the concepts of Greater Than, Less Than, or Equal to:


1).  Roll and Graph – Roll and Color Graphing – invite the children to roll one die at a time.  Have the children count the number of dots on each roll and color in the corresponding number of squares.   Ask the children which row has MORE than the other.  Note:  instead of a roll and color, the children can use manipulatives to place in each square according to the number rolled on the die.  The graph template can be cut out, laminated, and used as a horizontal or vertical graph.

2).  Two color sorting – set out two colors of manipulatives (counters) in one container.  Invite the children to sort the two colors into separate containers.  After counting each color, see if the children can determine which color has MORE than the other.  For younger children, do this activity as a group and count the number of items together.  Use only a small number of each color until the children gain confidence in sorting and counting.  Again, ask the children to use the “munching mouth” hand signs as you determine which color has more than, less than, or is the same.

3).  Stacking Cups – invite the children to play with paper or plastic cups.  Have the children stack two separate cup towers.  As a group (or individually) count the number of cups in each of the stacks.  Which of the cup towers has more than (or less than) the other?

Wikki Stix Minion Math Picture #44).  If your kids like MINIONS, we have a printable GREATER THAN or LESS THAN Math Game that uses Wikki Stix.  It’s another fun way to encourage kids to play with Math!
