Help! I can't remember the code! Year 3-4
Help! I can't remember the code! on PhotoPeach
This was a rich acivity for reading and writing numbers up to 1000. Lots of discussion took place related to Place value....what is the value of the 0. Can it be at the beginning of the number...how much is it worth in the middle/end of the number? If the code is between 500 and 800 could it be 450? If the number onely has one zero....could it be 600? Look for the clever number patterns we created as we tried to solve this problem!

Year 5...thinking flexibly using quick images
 |
| Quick images is an activity that encourages students to use groupings flexibly to determine how many there are in total. The image above and below is shown for 3 seconds...in those 3 seconds these were some of our noticings - I saw an array of 5 along the bottom and 4 up the side - that is 5 groups of 4... I saw 4+4+4+4+4...I knew that 4+4=8...double 8 is 16....16+4=24 I saw 2 groups of 10...2X10 = 20 I saw 2 groups of 8....8+8 or 2X8.....that equalled 16 + 4 =20 I saw 5+5+5+5....5,10,15,20...or 4 groups of 5...that is 4X5 which equals 20 What did you see and how would you represent and discuss your findings? |
 |
| Quick images provide rich opportunities to useflexible groupings, opportunities to discuss our thinking and what we visualised opportunities to represent our thinking in different ways opportunites to use maths language |

The Year 4's investigate temperature and thermometers.
 |
| We are looking at the maths and number when looking at temperature and the thermometer. |
 |
| We had to use our skip counting in 2's to read the temperature. |
 |
| When we put the thermometer in hot water the mercury increased to over 90 degrees celcius. |
 |
| The temperature in the freezer dropped to -4 degrees. |
 |
What do you notice? What do you wonder? Look at the actual temperature, 11.8. It is a decimal. 11 whole numbers and 8 tenths. This means the temperature is more than 11 degrees but not quite 12 degrees. How much will the temperature drop overnight? |
