Does it feel like we’ve already been in school for 100 days or more? You’re right!
Students celebrated 100 days of school on January 16 with a variety of activities. One of those activities was led by Resource teacher Ms. Huber.
Several fourth and fifth grade students worked on math goals by creating a list of 100 different number sentences that equal 100. Each student had just one class period to create as many number sentences as they could.
Ms. Huber said the students loved the challenge and were excited to show off their computation skills.
This challenging activity related to many math standards for fourth and fifth grade:
CCSS.Math.Content.4.NBT.B.4: Fluently add and subtract multi-digit whole numbers using the standard algorithm.
CCSS.Math.Content.5.NBT.B.5: Fluently multiply multi-digit whole numbers using the standard algorithm.
CCSS.Math.Content.5.NBT.B.6: Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
Students were also given math problems to work on at home that had to do with the number 100.
Examples included finding some people whose ages total exactly 100. One students’ response led to the following answer: Mom is 31, Dad is 35, one brother is 7, one brother is 8, a sister is 11 and a cousin is 8.
Another math problem students worked on at home was to create a word problem in which the answer equals 100. One student created this word problem: Ms. Huber had 6 heart shaped buttons. Daniel has 45 sailor badge buttons. Tom has 5 golden pearl buttons. Jimmy had 12 silver buttons. Lady Gaga had 19 gaudy pearl buttons. She also owned 13 worthless buttons. How many buttons did they have in all?
Wow! What great work! We are proud of each of your students, Ms. Huber!
Here are the 100-Day questions sent home with some of the students. Go ahead, give them a try!
- What can you do in 100 seconds? Time yourself and let us know.
ex.) How many times can you jump rope in 100 seconds?
- What 100 objects could you fit in a 5 oz. cup?
3. How tall is a stack of 100 pennies? 100 nickles?
- Make number sentences that equal 100.
ex.) 5 X 20 = 100 (3 X 33) + 1 = 100 (300/6) X 2 = 100
- Where would a 100-step walk take your from your house? From your bedroom?
- Find some people whose ages total exactly 100.
7. Toss a coin 100 times and graph the results… head and tails.
- List what $100 will buy. Get as close to $100 as you can.
- Create word problems where the answer is 100. ex.) Johnathan and Natalie walk 7 blocks to school every day and 7 blocks back home. They go to school 5 days of the week. On Monday, Wednesday and Friday they walk home, eat a snack and then walk to the park to play. The park is 5 blocks from home. They walk home again in time for dinner. How many blocks do they walk each week?
10. How many words can you make using the letters in ‘one hundred’?
