It helps to explain the concept clearer.

This reply came a bit late but acts as a reference for anyone who is looking for a thermometer in the future.


You can get a boiling point thermometer from The Learning Store at $3.20 each.

Encourage your child as they learn and clear their doubts.


When they are weak in certain foundations, questions would not help them but it is the simple little things at home like your pencils, straws eg to give them a concept to visualize and grasp like simple no concepts or you could use math manipulative to give them hands on

you could consider getting some manipulative from The Learning Store and also gather some web research to reinforce learning .

You could get the below from The Learning Store as well

Thanks but looks like we have to order a set of 10 and they will deliver only after a few weeks.

if you are referring to the boiling thermometers, set of 10, they are in stock too.

well, we have other thermometers which are not listed on the web that are ready stock.


Let me know if you are keen.

you may perhaps ask them to visualize in forms of things they are familiar with or illustrate with pictures or actual objects.


in p1s, it is important to build their concept up as it is a foundation
hope things work well.

they might look like lego but they are not.


the small units you see inside represents one , the rods represent 10 and the hundreds is represented by a flats and a thousand is represent by a cube.

For example illustrating 4 + 8

you will put 4 units one side and 8 units one side.

Using the tens concepts - you will remove 6 units to form a 10 and left with 2 units to illustrate the answer is 12.

buds,

ds2 don't really have number concept. while he can count concrete objects, he can't imagine adding (or subtracting) them up. ie, he can look at the concrete objects while adding and just count the added up qty to get the answer, ie he see 4 pencils and sees another 4 pencils and he count to 8, but he cannot understand 4+4 is 8.
how to 'teach' understanding of addition and subtraction?
when to progress from concrete objects addition to abstract number addition? TIA.

maybe base ten will help?
