First Cast Math: Telling Fourth Dimension 1.Md.B.3

Hello!

Welcome to Math activeness Thursday!  Link upwards your math post service at the bottom.  I can't hold back to encounter your activities!

Today mine is on telling fourth dimension amongst the hr as well as one-half hr as well as a thumbs up, thumbs downward activity.

Activity name: Thumbs up, thumbs downward (perhaps in that location could live a improve title, but creative juices aren't flowing at the moment)

Concepts: 1.MD.B.3 Telling fourth dimension for at the hr as well as one-half hour, checking for accurate hr manus position.

Supplies: Little clock faces for each student.  I flora this slap-up 4-pack at Dollar Tree.  The picayune plastic hands are decently sturdy (not certain how long they volition final but certain improve than paper).

Time needed: 20-30 minutes for teaching, practicing, checking, as well as playing amongst the clocks.

Instructions:  Take 5-10 minutes teach. Talk virtually the the hr seat as well as if they withdraw to review which manus reads the infinitesimal as well as which manus reads the hour, produce hence now.  Explain, at the top of the hr nosotros are only starting a novel hr as well as the infinitesimal manus is at the top.

Digitally it looks similar 1:00.  Show other hours past times moving the hr manus but hence come upwards dorsum to this one.

Explain that each of the picayune dots inward dark is i infinitesimal passing as well as when the infinitesimal manus passes each of the numbers nosotros truly exercise skip counting (AKA multiplication) of 5.  But for now, nosotros are going to brand the infinitesimal manus larn to the bottom.  How many minutes is that?  We could count each of them or nosotros could skip count--it's 30!  Then why produce nosotros telephone telephone if one-half an hour?  Lets await at the clock equally a circle.  If nosotros shade all the minutes nosotros passed from 1:00-1:30 that is one-half the circle.  It is one-half of the whole hour.  (But hither is the business office nosotros don't ever teach) While the infinitesimal manus is going, does the hr manus remain inward the same place?  No, it advances slowly, getting closer as well as closer to the adjacent hour.  So when the infinitesimal manus is at the one-half hr position, lets encounter where the hr manus points.

It is one-half means betwixt the 1 as well as 2.  Yes, that is because it is one-half means through the whole hr of minutes.

If you lot saw a clock similar this

 or this

it only wouldn't seem precisely right.
Let's encounter if you lot tin approximate which i of these clocks accept the right manus position.  (put ii clocks side past times side as well as brand i right as well as i wrong as well as produce this a few times).
Now you lot are fix to try!  Practice as well as play.  Play could include reading a storey amongst times inward it as well as the children motility their clocks each fourth dimension it says the fourth dimension inward the story.

Have fun!

Now it's your fourth dimension to link upwards if you lot want.  Here is the 1st flat MaTh template.

We volition live doing 1st flat math for the remainder of this calendar month as well as hence inward September we'll live into sec flat math.
