Number Ninja's

IALT:Write about what I did in Maths

Today in class I worked with Losana today on our Number Ninja's follow up task.The Task were all about estimating how much we think things weigh.I found this activity pretty challenging because I wasn't really sure what I was going to estimate but with the help of Communication we found the answer in the end.Here is our work that we have finished and please leave a comment if I made a mistake.😀💬

Follow Up Task - Number Ninjas

• Mililitre
• Metre
• Kilogram
• Centimetre
• Milimetre
• Gram
• Ton

Which one of the units on the list would you use to measure these?

The time it takes to…

• Bake a cake  - I think that I would use Grams because Gram is a common measurement of cooking that people would use.
• Count to ten - I would prefer Centimetres to measure counting to 10 because, in my opinion centimetre is the shortest measurement I would prefer to use.
• Eat an Ice Cream- I would use Gram instead of ton because a ton of ice cream would be heaps and people would mostly only eat 2 scoops of ice cream.
• Cycle from Dunedin - Nelson - I would use metre to time this because it’s the furthest measurement I would use other than kilometre.
• Check your emails - Centimetre because checking my emails doesn’t take long therefore centimetre is a small measurement.
• Fly from Wellington - Auckland - Metre, because in my eyes out of all the options we have to choose I find that Metre is the biggest measurement out of them all.
• Play 5 songs from a playlist- I would choose a meter because each song is like about 5 to 7 minutes long
• Heal a broken bone - I would use a ton, to measure this because healing a bone does take a while, and therefore I find ton as a taking time of a measurement.
• Blink 10 times - I think that I would use a Centimeter because it’s longer than a millimeter.
• Grow a large tree - Ton, because it takes a while to grow a large tree, and especially weighing it could be harder than it sounds therefore I would prefer to use a ton to measure this.
