Dwire+March+Math+Length

(Week 1: Go through lesson as is.) (Week 2: Review lesson, use measuring tape and have students practice using the measuring tape.)

For math this month we are going to discuss what "length" and weight are and how to measure these things.

First, look at these toys. Can you tell me something about them? Are they the same size?



The words we are going to talk about today are length, short, long, shortest, and longest.

Length is the extent of anything from one end to the other.

Something with little length.

Something with a lot of length.

The smallest thing in a group.

The biggest thing in a group.

Lets take a look at these two lines. Line A is shorter than Line B. I can tell because I can look at them and see that they are different sizes. Is there another way to see if they are different sizes? What if I measured them? (use measuring tape to measure lines).



What did measuring the lines tell us? Do we always need to use a ruler to tell if an object is short? (no, sometimes you can just look and tell)

Let's figure out which objects are bigger/smaller by just looking at them.



Now lets look at some other pictures and figure out which objects are the shortest and longest.
