- Estimating - The student will be able to estimate the cost of three new items and the length of time necessary to save the money for those items.
- Finding circumference, diameter, and radius - This activity will allow students to measure the circumference, diameter, and radius of a circle in a hands-on way. By being able to manipulate a circle and stretch it out the idea of circumference will be more concrete. Students will use each other, desks, and chairs to create circles that can be measured.
- Finding Square Footage - The student will be able to calculate the square footage of a given area.
- Graphing - This activity will introduce graphing. The teacher will guide the students as they work together to develop questions, set up a blank graph, interview other students, and fill in the graph with the results. A teacher created worksheet can be completed at the end of the activity to reinforce the concept.
- Introducing a standard unit of measure: the foot - This activity will introduce the concept of a standard unit of measure. Students will measure various objects in the classroom using their own feet and a ruler. By comparing their results with their classmates, they will be able to see the value of a standard unit of measure.
- Math on a Map - Students will practice finding a variety of information using a satellite picture of their hometown. This would be a great activity to use for review or when there is a substitute.
- More or less (or the same) - For this activity, students will work in pairs to play a game. The teacher will introduce the concepts of more, less, and the same. The whole class will play a game with the teacher using dominoes before dividing into pairs to play the game.
- Ordering Numbers - Students will work together to practice ordering groups of six and seven numbers. They will use their phone numbers and birth dates written on index cards.
- Patterns - This activity will help students see the logic of creating patterns and help them begin to be able to create their own.
- Percentages - Students will be able to apply percentages to real life situations by figuring the amount of income tax that will be withheld from a salary.
- Plotting points on a graph - The students will use graph paper to plot points on a graph. When the points are connected they will make a familiar shape, number, or letter. They will practice reading co-ordinates to each other, as well as, practice plotting them. The activity is meant to be fun and light, not competitive or stressful.
- Polygons - The students will explore and create a poster design using polygons. The posters will be displayed in the classroom and students will be challenged to name as many of them as they can. This activity will allow students a tactile, expressive way to learn about polygons.
- Roman Numerals - The student will be able to recognize and name roman numerals up to twenty.
- Rounding to the nearest five - Students will enjoy practicing rounding numbers as they try to be the first to cover all their numbers in this game of Bingo. The teacher can set the pace for this game. It can be set at a beginning level with a lot of discussion and helps or it can be played as a speed round where students are racing to find the right numbers.
- Symmetry - The student will be able to identify objects that are symmetrical and draw half of an object by looking at the other half.
- Using Tangrams to Find Patterns - Students will create patterns using tangram pieces inside a shoebox lid. After they have placed the pieces in the lid, they will count how many shapes there are. So, if they use triangle shapes, they will count how many different triangles there are in the shoebox lid.
- Value of Coins - The student will be able to choose the appropriate combination of pennies, nickels, and dimes needed to total the amounts listed on a series of five index cards.
