To subtract: 31 - 14 Set out 3 tens and one one. You cannot take away 4 ones yet. Trade one ten for 10 ones; now you have 2 tens and 11 ones. Now you can subtract one ten and 4 ones, leaving 1 ten and 7 ones, So you are physically going through every step of the process. Wendy P of Math Cats top. Tammie, here are most of the activities that I do for calendar math: My bulletin board consists of I begin by crossing off the number 1 on the 's board. I then put up one tally mark on my chart paper that is posted under it.
I then add 1 unifix cube to the one's section of the "box" and I put an index card with the 1 on it under the ones section to show the I have made. I then add 1 penny to the zip loc bag and write 1 cent on a post-it note and display that. I then make my clock say 1 minute after 9 and write the time on a post-it note and display it under the clock. I then add a card labeled "1 cup" to a special place on the board as well.
I then display a shape of the day on the board and we discuss the properties of it. As you can see, after the 9th day of school for example, you add 1 more cube and then you can change your ones in for a ten, your nickel and 5 pennies for a dime, etc. I have also added measurement Day 1 is 1 inch, and so on.
I also have them make as many equations as they can that will equal the of the day. I write some of their ides an a chart. I then announce "teacher's turn" and I model some "incredible equations. I hope this makes sense. Kaye, on teachers. Is there anything to keep track of the tens? I take the 10 ones that I made from the cubes and link them together into a "ten.
I continue to do this until we reach , in which case I remove all of the tens and trade for a hundred the hundreds that came with my math kit. They are made out of wood. I continue on until the last day of school. I have seen people use straws, and I think that will work fine too. I just want to use the unifix cubes because that is what they see in their math books and on our end-of-grade tests and I want to be consistent with that.
They even make a special pocket chart for the straws now. Underneath my hundreds, tens, and ones section I have a copy of a blank hundreds board that I ran off. As we add a one each day I color in one cube on the chart to show how to graph what I have modeled with the cubes. This helps move them from the concrete to the picture level.
I drew off blocks to represent this and I cut out squares from construction paper and laminated them to fit in the blocks and labeled them. On the 1st day I put up one square. That was 1 cup. Next day I added another square and that was 2 cups. I moved them both to the pint section to show 2 cups makes a pint, etc. We go on til we get to a gallon. I have even used real water and added a cup a day til we got to a gallon and demonstrated all the conversions along the way. I hope you can make sense out of this!
Sorry this so long but I think the calendar is a great tool. I can't seem to get my kids to learn how to tell time, count, etc. Is this too much information or what? But I would like to tell you that I have made what I think is a big improvement to the board.
Instead of using the ziploc bags for the money section, I bought the big money bulletin board set and laminated the pieces. Next article on place value: Decimal Place Value.
