For this activity, students listen to the story, The Enormous Watermelon, and solve a problem using pictures, numbers or words to show how they solved the problem.

Students estimate the quotient of a 3 digit number by a 1 digit number.

Students work with a partner to estimate and measure the weight of a set of small classroom objects and record their findings on a chart.

Students explore multiples using snap cubes and hundreds boards and explain patterns discovered on each hundreds board.

Students work with a partner to cut out different sized open boxes and fill each box with cubes to find the volume.

For this activity, students work with a partner to toss two-colored counters and find two numbers on a grid that equal 10. Students write the addition fact and continue taking turns until all pairs of numbers that equal 10 have been found. Students count to see who recorded the most facts of 10.

Students are given an elapsed time word problem to solve in this interactive resource.

Students read the clock and find the elapsed time based on the question presented in this interactive resource.

Students select three different rectangles and determine the number of color tiles needed to cover them. Students sketch and label the rectangles in order from least to greatest area and complete sentence stems about the rectangles.

Students determine the unknown whole number in an addition or subtraction equation relating to three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8+ ? =11, 5 = ? ? 3, 6+6 = ? Game board templates are provided.

Students work with a partner to build two different rectangular prisms out of centimeter cubes. Students then find the volume of each individual prism, then join the prisms and add the volumes in order to find the total volume of the new prism.

Students demonstrate their understanding of counting and cardinality by playing a game of concentration. After shuffling the number cards and placing them face down, students take turns turning over two cards, one at a time, saying the number on the cards. If the cards match, the students keep the cards. If the cards do not match, the cards are placed face down. The game continues until all matching pairs have been found.

For this activity, students work with a partner to flash and build five frames.

For this activity, students work with a partner to roll a die and identify five frames that have the same amount.

For this activity, students work with a partner to take turns holding up a numeral card and building five frames.

Students draw a picture in order to show the decomposition of a whole using sixths.

Students are given a problem to solve involving pizza and fractional portions. Students use the information in the problem to determine if the boys in the problem ate the same amount of pizza, explain their answer, and justify their conclusions using a visual fraction model.

Students use geoboards to make a quadrilateral. Students copy their quadrilateral onto geoboard paper and record as many different quadrilaterals as they can and tell how the quadriaterals are alike and different.

Students make a square on a geoboard, draw the square on geoboard paper, and cut it out. Then students make a square that is bigger or smaller than their first square, draw it on geoboard paper, and cut it out. Students continue to see how many different sized squares they can make and draw. Lastly, students paste all of their different sized squares onto a sheet of paper in order from smallest to largest.
