Students measure the length of a gummy worm with a ruler. Students stretch the gummy worm as far as he/she can and measure the stretched gummy worm. Students identify the difference in length between the original and stretched gummy worm and record their findings.

Students decompose numbers less than or equal to 10 into pairs in more than one way by using objects or drawings, and they will record each decomposition by a drawing or equation (e.g. 5= 2 + 3 and 5 = 4+1).

Students partner up and take turns guessing each others decimals. Students must read the decimals correctly and match them up with the correct decimal in standard form.

Students interpret the data in a bar graph and use it to answer the questions about the graph in this interactive resource.

For this activity, students work with a partner to discover the number of ways they can make one whole using fraction pieces of the same shape and size.

Students use a deck of cards to make two 5 digit numbers and add the two numbers to make the largest sum possible.

For this activity, students roll a die and use counters to make sets of numbers equal to or greater than the number rolled. Students use pictures, numbers, or words to show their work.

Students take turns with a set of measurement concentration cards to determine if the measures shown on the cards are equivalent. Next, they complete the math sentence. The cards template is provided in the activity.

Students measure classroom objects to the nearest one-eighth of an inch and create a line plot to display the data.

Students looks at three paths and predict which path they believe will be the longest and which will be the shortest. Using rulers, yarn, or string, students measure the length of each path and record their findings.

Students work with a partner to arrange a set of number cards in order and take turns closing their eyes while the partner removes a card. The other student guesses the missing number by saying, "I think ___ is missing because..." The partners continue to take turns to remove a card and guess the missing number.

Students fill in missing numbers on a number grid. It reinforces students' ability to write numbers from 0 to 20.

Students will determine the unknown factor in a division equation in tihs two-player game. They will take turns choosing a number card 1-10 until they find a factor that completes the unknown of the division equation. This activity can be used during small group instruction and later moved into a center activity to assist students master division facts. It includes four sets of division cards.

Students work with a partner to sort containers into three groups according to their prediction of which container holds less than 1 liter, about 1 liter, and more than 1 liter. Students check their predictions by measauring the capacity of each container using metric units.

For this activity, students listen to a story to solve a problem. Students count out 10 mice and place some inside the jar and some outside the jar and use pictures, numbers, or words to show the many ways the ten mice could be arranged.

Students use the strategy of doubling one factor and halving the other factor.

Students multiply a whole number by a fraction or a mixed number and represent the problem using a model.

Students multiply a unit fraction by a whole number using a model, number line, and an equation.

Students solve problems and choose three other two-digit numbers between 10 and 100 multiplying each of them by 10 to the first power, 10 to the second power, and 10 to the third power. Students explain the pattern they notice in the product when multiplying a number by powers of 10.
