Allanah's strategies for Maths 

Use the following strategies to answer the questions below

Strategy making hundreds

153 - 89 =

153 - 100 = 53

53 + 11 = 64

322 - 57 =

322 - 100 = 222

222 + 43 = 265

162 - 86 =

162 - 100 =62

162 + 14 = 176

218 - 39 =

218 - 100 = 118

118 + 61 = 179

Rounding and compensating

133 - 89 =

133 - 90 I added one to 89 to  make it 90.

133 - 90 = 43 + 1 = 44

320 - 57 =

320 - 60 i added 3 to make 60

320 -60 = 260 + 3 = 263

124 - 86 =

124 - 90 i added 4 to make 90

124 - 90 = 34 + 4 = 38

Allanah's changing sound questions and missing words

Questions

1. What is sound? sound is a form of energy
2. How is sound produced? for sound to be produced it must be set up by a source
3. What do sound vibrations travel through? vibrations travel through a solid liquid or gas
4. Through which substance does sound travel fastest?Concorde travels faster
5. Why is this? cause things that travel faster is called super sonic that is Concorde
6. Why do you think sound cannot travel through a vacuum?
7. What is pitch? pitch is when something sounds high or low
8. How would you create a high pitch on:
1. A guitar? A shorter thinner tighter string will produce a higher pitch
2. A recorder? A short column makes a higher pitch
3. A drum?
9. What does the volume of sound depend on? sound depends on the amount of energy the vibrations contain and rate at which this energy is transmitted
10. How would you play a drum quietly? if you hit the drums hard it would make a loud sound if you hit it softly it will make a quiet sound
11. How much energy do you think the vibrations would have if you did this? if you did this you would take up a lot of energy from vibrations
12. If the vibrations had lots of energy, what would the volume be like? it would be a high pitch

Use the words below in the reading passage.

           Changing Sounds

Sound is a type of  energy.   Sound is produced by vibrations.

Vibrations are made must by __hitting___ a  drum, __blowing___ a recorder,  _plucking____ a string.

_sound ___ can travel through a solid _  liquid__ or gas and reach our ears where it can be heard.  If the vibrations have a lot of energy then they are __long___.  If they have little energy then the sound is __quiet____.  Sometimes vibrations can be __felt_____ on the skin.

Sound travels faster in a solid than in _water__.  It travels faster in water than it does in _air____.

Dolphins communicate with each other under the _sea__.  

Pitch is the highness or lowness of a sound.  A high__ pitch is caused by short vibrations and a low pitch is caused by __long_ vibrations.

The pitch of a note produced by a guitar depends on the length, thickness and tension of the string.  A shorter, thinner, tighter string produces a high pitch and a longer, thicker, looser string produces a low pitch. On a guitar the strings can be shortened by putting a  __finger_ on the fret board.

When you _blow_____ into a wind instrument the air vibrates.  The pitch depends on the length of the column.  A long column makes a _low ___ pitch and a _short___ column makes a high pitch.

The loudness (volume) of the sound depends on how hard a string is plucked.  The sound will be louder the harder it is plucked.
