Apple Seeds

This K-2 activity lets students practice number recognition, counting and writing the

numbers 0 through 6

Base 10 Hundreds Chart

Use a random number generator and base ten blocks to add and subtract with the Hundreds Chart.  A good teacher utility

Clean Up the Playroom

Practice Ordinals with long names and short names as students move objects to the shelf to clean up their playroom.

Factor Trains

Use multilink cubes to visually see the Greatest Common Factor and Least Common Multiple in this hands-on manipulative and coloring lesson.

Domino Fractions

Play domino fractions and learn the magnitude of proper fractions in this game for two players or teams.

Count On with Christi

Count along with Christi as this interactive lesson gives students practice in Counting On.

Feed the Hungry Fish

A SMART board lesson based on an activity from an NCTM Illuminations lesson. Black line Masters included.

Fill the Egg Carton

A game that involves the students in counting as they roll the die and help Henrietta the Hen fill her egg carton.

Harley High Low

Harley High/Low is a fun little problem solving activity that can be played at the students desk with a standard deck of cards.  This can be used as a large group or class activity.

Fraction Wall

This lesson allows the student to move fraction bricks to compare and combine the proper fractions in an effort to rebuild the wall.

Can be utilized with fraction rods or Cuisenaire Rods

Fill the Ten Frame

Primary grade students practice filling the ten frame with red counters while practicing the strategy of anchoring to 5  and 10.  Teacher questioning is important during the lesson.

Make the Larger Number

This “game’ deals with having a single digit random number generated and placing the number at a place value location so that your end result will be a larger number than your opponent

More or Less

Roll the die and spin the spinner as your primary level students practice the computation strategy of One More/Two More

or One Less/Two Less

More Less Dot Cards

This lesson uses Dot Cards to expand the concept of More, Less, or Same.  Dot Card blackline masters are included for students to have their own set.  The lesson progresses to using numbers and symbols at the end

Relative Magnitude

One student places a secret number on the number line and others try to guess the number. As others guess an arrow is moved to indicate their guess on the number line.  Four variations of the lesson are included.

See Hear Count Write

The senses come into play here as primary students can see the number, the name, hear the name, count the objects and writing the number.  Use the Creative Pen to add to the lesson.

Skip Counting Circles

Birds On A Wire

An interactive lesson with ordering single digit numbers, even and odd numbers, and Less Than greater Than

More Less Same

This activity involves comparing numbers with more, less, or same.
