Kassidy gets on MobyMax 33 minutes each day for 5 days. Which is the best estimate of the total that she gets on for 5 days?

33+33+33+33+33=165

200 minutes = estimate

Co Van swam 4.42 meters on the first day. She swam 6 meters on the next day. If she swam x meters on the 3rd day, which equation represents this if she swam a total of 18.23 meters total?

4.42+6+x=18.23

Minh-Anh has 30 pencils. Her brother has 10 less than her. Draw a strip diagram that represents how much they have total.

Strip diagram that shows 50 total on the top and     30+20 on the bottom.

Create a dot plot to represent how many times each person in Co Van's class went to the store in a month.

Times         Amount of people

   1                     3

   2                     1

   3                     1

   4                     3  

On the bottom, there needs to be 1, 2, 3, and 4 and then those are labeled as times that each person went to the store in a month. On top of 1, there needs to be 3 dots. On top of 2, there is 1 dot. On top of 3, there is also 1 dot and on top of 4 there are 3 dots.

Nguyen logged on to MobyMax each day for 11 minutes. If he logged on for 7 days, what is total amount that he logged on? Estimate that total.

11+11+11+11+11+11+11=77

77->80 = estimate.

Mrs. Appling drank 9.57 cups of water in 1 day. On the 2nd day, she drank 4.52 more cups than she did on the 1st day. Which equation represents X, the total amount of water that she drank in both days?

9.57+9.57+4.52=X

Mrs. Singer had 440 stickers to give away. She gave 140 away on the first day. If she gave the same amount for the remaining 3 days, draw a strip diagram that would represent X, the amount she gave on each day for the next 3 days.

The total would be 440 on the top. On the bottom, one box would have 140 and this is the largest box. The rest of the 3 boxes would be a little smaller than the first box with 140 but would be the same size and labeled with x.

Hanna ran a race in 24.52 seconds. Minh-Anh ran the same race in 5.24 seconds more than Hanna. What is the best estimate of how many seconds they ran the race altogether?

24.52+24.52+5.24=54.28 seconds

54.28 ->50 seconds = estimate
