Can someone help me with my DS 1st Grade Homework?

:confused: :confused: ???

There's got to be some info missing. It makes no sense to me. Let us know when/if you figure it out. Good luck!
 
I don't know if I saw the entire page when I clicked on your link but I'll try to help. It looks like they are beginning to learn about place value. The single squares in the first problem represent "one" each. The long ones in the second problem are usually called tens rods. They represent a group of ten. At school they probably have little yellow or blue cubes, rods and flats. The cubes are ones, the rods are ten and the flats are 100. The students can exchange ten cubes for a a rod (long ones) or ten rods for a flat (the flat is made up of 100 little cubes put together.)
So in the first problem there are 16 cubes, that is the same as one rod (long one) and 6 cubes.
H (hundreds) = 0
T (tens) = 1
O (ones) = 6
In the second problem I only see 6 rods. That is only 60 so it is not enough to exchange for a flat.
H = 6
O = 0
I hope that helps!
 
In the first problem they are asking him to exchange the single blocks for 10's or 100's. There aren't 100 there so you really only need to worry about the 10s.

In the second problem you can exchange 10 rows of 10 for one 100. Any remaining 10s would be listed in the Tens column and then any single ones left over would be listed as Ones.

Hope that helps.
 

I've seen these "boxes" used before for DD's math homework. Seeing how she is now in 4th grade and I'm not sure if this is the same thing.

Looks like he needs to count the boxes where they are all linked together in sets of 10 and then separated in singles and put home many "hundreds", "tens" and "ones" are in the total of the boxes for each problem.

Example: total of 123 boxes

1-hundreds
2-tens
3-ones

Hope that helps! But it seems kinda hard for a first grader, unless our schools are that much farther behind yours!:eek:
 
All I can tell you is that 10 of those little squares = 1 long. 10 longs or 100 little squares = 1 flat.

I agree it is about place value. I use these with some of the children in my class. 1 cube = 1 unit, 10 cubes = 1 ten and 0 units (or 1 long) and 100 cubes or 10 longs = 1 hundred, 0 tens and 0 units (also called a flat.)
The answers to the questions therefore are. Question 1) 1 ten, 6 units.
Question 2) 1 hundred, 0 tens, 3 units.
I agree that this should have come with some explanation. I always make sure there is an explanation and an example on the homework I set my class (7 year olds.)
 
Ok....my son just came home so I asked how he would do it:

He said: The first one is 1 long and 6 cubes.

The second one is 10 longs and 3 cubes which Equals 1 flat and 3 cubes.

Thanks guys. I will explain it to Pete now that you've explained it to me. :p His homework comes with little or no instruction sometimes ever since his teacher has gone back to school to get her masters. :(
 
I guess the second problem has more than 6 rods in it. I wonder why I can't see them all.
Good luck with helping your son with his homework.
 
ITs a place value system. It is there to help students realize place value and numeration.

Its pretty straighforward.. think about it as a visual approach to math
