Q&A - P1 Math

[stacey_berry]

Hi,


Anyone knows where to get this book "the essential parents’ guide to primary math "?

Hi parents


need advise for division question:

12 divide by 6 = 2

if there are 12 objects, does the child group by circling 6 objects or 2 objects?

Should my explanation be : 12 objects shared among 6 friends and each friend gets 2 ?

or 12 objects shared by 2 friends and each friend gets 6?

Which is the correct explanation?

Hi, with ref to ur ques:

12/6 or 12 divide by 6

It means for instance divide 12 sweets equally among 6 frenz;
How many sweets do each fren get?

So 12 divide by 6, u shud circle the sweets in 2s for each fren. There are no leftovers and each fren gets 2 sweets equally. 12 divide by 6 equals 2

U can illustrate using manipulatives; anything u can get in hand like colour pencils. I hope this is helpful.

Hi PreciousLife


Thanks for your advice.

Ok, I've managed to scan the question from the book. Here it is.


http://i46.tinypic.com/34yuq2s.jpg\">
On the next page, it says \"How many other ways can she arrange the cards?\" Draw all possible answers in the space below.\"

Finally, the last part has a question, She can arrange the cards in ____ other ways.

Thanks!

The answer should be 6 ways. But when you fill in the answer, it should be She can rearrange the cards in 5 other ways.
Working:
12 shared by 1 group = 12 in each group
12 shared by 2 groups = 6 in each group
12 shared by 3 groups = 4 in each group
12 shared by 4 groups = 3 in each group
12 shared by 6 groups = 2 in each group
12 shared by 12 groups = 1 in each group

Hi can anyone help me with the following qns?

Ryan, Grace and Charlie have 100 bottles of jelly beans altogether. Charlie has 37 bottles of jelly beans. Charlie gave Ryan 11 bottles of jelly beans and Ryan had 46 bottles. How many more bottles of jelly beans does Ryan have than Grace at first?

Working:-
Total -100
Charlie - 37 - 11=26
Ryan - 46
Grace - 100-26-46=28
Since Ryan has 11 bottles from Charlie, then he should has 35 bottles at first.
My answer - Ryan has 7 more bottles of jelly beans than Grace. As I don't have the answer sheet with me, not sure whether my answer is correct or not.

Answer is 7
You need to draw model for this type of question but it's too troublesome for me to draw here. I just explain.
100-37=63
63+11=74
35+11=46
74-46=28
46-11=35
35-28=7
Above working based on model drawing

Reading through the threads, I feel it’s important to realise why model drawing and number bonds are taught at an early age.


My girl is now in P2. Like many parents, I learnt number bonds & model drawing together with her. Initially, i have the same familiar grouses (too difficult for P1, algebra is easier & more suitable).
After much practising, I have began to appreciate the usefulness and extensibility of these concepts. Once well-acquainted, it allows the child to use a single model drawing concept to solve higher-order questions using basic part-part-whole concepts. It brings them back to the basics. It will broaden and deepen the child’s thinking (which will serve them well in future), rather than focus on applying "already developed/derived" methods/techniques which hide the basics and can have limitations when they hit more advanced questions that push the boundaries of their understanding.

can any parent here advice me how to explain to my child the concept of come after

e.g.
a)15 comes just after what number
b) what number comes just after 14

[sembgal]

Make number cards and teach the child what comes before and after. Explore and have fun. This concept children should master before go P1.

I faced this problem too a few weeks ago, but a few daily practices and my boy now knows.
I started by asking him if he brushes his teeth before he sleeps or after he sleeps at night. Before. Thenwe do some verbal exercises on before. Then move on to you brush your teeth after you wake up or before you wake up. After he gets the After concept, we do some verbal exercise on After.
Then we mix the questions. Whenever he gets confused, we go back to that two questions to reinforce before and after concept.
You can use a number line too.
