Over the past few days we have continued to learn about hearing and sound. We watched a video from Bill Nye and worked together to answer some questions. Here are some interesting facts that we learned:
- Sound is vibrations of air
- An echo is when a sound wave is reflected
- Frequency is how fast or slow a sound wave is moving
- Sound can be timed to see which direction it came from
- An ultrasound machine turns echo into pictures
We have had a spelling test that has taken us 2 days!! We were tested on our knowledge of our grade 4 no excuse words. We have 96 words on this list. Ms. Binks is going to mark them and see if we got any words incorrect. These will be words that we will need to work on throughout the upcoming weeks so we don't need to always be looking at our word list when we are writing. We will have our tests marked and returned by next week.
We started Number Detectives this week. Ms. Binks gives us a choice of 3 numbers (along with a bonus number) and we have to figure out these 10 questions:
1) Write me in words
2) Show me in base ten blocks
3) Show me using tally marks
4) Skip count to me
5) Show me in expanded form
6) Show ways to make me using addition
7) Show ways to make me using subtraction
8) What is 10 more than me?
9) What is 100 more than me?
10) Add the digits together
Students who are looking for extra practice with their math skills can complete the number detectives activity at home.
