Additional Ideas

 

1. Have students work with representations of numbers using base ten blocks, ten frames, or drawings such as sticks and dots. Have students make or draw different numbers and explain if they are greater/less than other numbers. Students can also use technology applications such as Base Ten Blocks Virtual Manipulatives Links to an external site. to make their representations.

2. Place value dice can be used for generating numbers to compare or use during comparison investigations.


3. Have students play “Roll and Compare” with a partner. Students roll two different colored die. Assign one colored dice for the tens and the other colored dice for the ones. Each student in the pair rolls and records their number. They compare their two numbers. Whoever has the greatest number earns one point. Or whichever student has the least number earns a point.

4. Another version of the game “Roll and Compare” can be played with using a number line to 70. Students find their rolled number and compare them using the number line. Students can record by writing a comparison sentence (e.g.: 54 > 32)

5. Cut up a hundreds chart Links to an external site.so that each number is separate from one another. Place the numbers in a bag. Students can play with a partner or in small groups. Have students draw a number from the bag and compare it to their partner’s or to the other people in their group. If they have the greatest/least number they earn a point. The person with the most points at the end of the time period wins. Extension idea is to put the students into groups of four or six. Have each student in the group draw a number from the bag and then line up from least to greatest. Each group can check the other groups for accuracy.

6. Give students a t-chart worksheet that has Less than 50 on the left side and Greater than 50. Give each student small cards of numbers (e.g.: 35) and also with different names for numbers (e.g.: 50 + 12). Have them sort the cards on the t-chart.
