Question: what is a good lesson to teach measurement to first graders? 

Answer: I think this will work with this age group been a while I have work with Children this age.\nI like the Glass of water. This is fun to do! Take two DIFFERENT Glasses, one narrow and tall and one short and fat! Then in front of the Children fill a Measuring Cup with ONE cup of water. Pour into glass number one. Then repeat pouring into glass number two! ;-D  Ask them to pick which glass has the most water!!! Hee, Hee. It so fun, most times they pick the Tall narrow glass because, well, it look like MORE!! Ha!!! Then you can explain Measurement Concept using the measuring cup, show them it the Exact same! BUT, because the glasses are shaped Different, one look like it have more! Hope you understand what I saying. Then you can work from here to TEACH the importance of using different measuring Devices to Really know what is correct!! It a blast! Just be Patience, as, it can take time for Children to see this Concept.\nIK has a good one with the Candy Bar. What I do is a one-on-one here, so fun, you take a candy bar and say you going to half it with a Child. Then Break it uneven (3/4-1/4) and measure the two pieces side by side so the child see one is bigger!!! Then you keep the big one and give the smaller to the Child, hopefully he/she will respond yours bigger! Then you say sorry and put the two pieces back together, so child sees, and Bite them off even eating that part, then you say; "there, now it even", and hand them a piece!!! It is GREAT!!!!! Then you can use a Ruler to show how this could have been done Fair!\nHEY!!!! Better add this, IF, you do the candy bar, be sure you know what candy a child can have. As, in, Dibetic etc. AND, be prepared to gain a little weight! ;-p AND, have a whole candy for them to take home, then, they not feel cheated!
