## First Grade Math Games Online

I came across this website this evening that lists some simple, but cute computer math games appropriate for first graders. I’m not that great about having LD use the computer for these kinds of things, but I think I’ll make a more concerted effort to make games like these available for him.  I think he’d enjoy them. http://www.internet4classrooms.com/skills_1st_math_new.htm Here are some examples of games listed at this website: 1)  Your...

## Jack-o-Lantern Math

We have little jack-o-lanterns and some Halloween-themedbeads that we’ve used for math in various ways. Today, DDhad to choose four cards, count out that number of beadsand put them into the jack-o-lantern. It helps with one-to-one correspondence. For LD I’ve used these same items for addition and skipcounting practice (basic mulitiplication groupings). ED just likes to put the beads into the jack-o-lantern whichI let her do if I can sit...

## Workbox Activities

On Tuesdays, I volunteer to help with Kindergym. Wehelp set up. Even LD (who is technically too old for it) hasa good time because his buddy often stays home fromschool so they can play together. ED (20months) lovesall the equipment. Here are a few things that were in our workboxes for theafternoon — tangrams, the hundred’s board puzzle andskip counting 2 to 200 maze (which I laminated). I found the...

## Skip Counting by 3s

LD is learning to skip count by 3s. He set up the wagonsand then put groups of three mini-erasers above eachwagon. To get him familiar with the general concept ofmultiplication I talk about groups of 3 (1X3 is one group ofthree; 2X3 is two groups of three, and so forth) and had him putthe seals under the appropriate wagon wheel. wagons and seals are available at filefolderfun.com Please like &...

## Math — Estimation Activity

We took a handful of mini erasers and put them on the table.Everyone had to make an estimate of how many erasersthere were in the pile. I guessed 75, LD guessed 90 andDD guessed 97, though she wrote it backwards. “Don’tLOOK!” she admonished me as she bent over her paper.It was the first time she’s ever written numbers and shestudied our numbers carefully to do it and to make herown...

## Math — Place Value

Here are a couple of our math activities. It’s been aboutsix weeks since we last worked with place value, so we’redoing some review. We used purple dots from MontessoriMaterials (see side bar); you can print them out for free.For 1000, I put ten 100s together with a brad. In the second picture, we are using an activity fromPeggy Kaye’s Games for Learning. This is a wonderfulbook, probably one of THE...

LD has been working on his addition facts.  Here are some of the activities we’ve done in the past few months. We often do two or three different math activities (not necessarily all addition related) and/or our math curriculum, Right Start Math. Right Start Math has some wonderful games; I recommend their math card games set; You can check it out at http://www.activitiesforlearning.com/index.asp?PageAction=VIEWPROD&ProdID;=12 if you’re interested. Pictured below is a...

## More Math Addition Activities — 2

Math balance from Right Start Math — my kids love to play with this http://www.activitiesforlearning.com/index.asp?PageAction=VIEWPROD&ProdID;=53 LD was SO excited when he saw it out today. “Hey Mom, it checks my answers!” By the way, our dining room table is always covered in stuff… sigh… DD just loves doing math when LD has math time. She literally comes running down the hall if LD and I are going to do another...

Egg carton toss — They threw two pom-poms into the egg carton and added the numbers together. They could use the abacus if they wanted. Math Monster– (ie. Freeze Tag!) Give the child the ANSWER and spread the equations around the back yard. You are the Monster trying to freeze them before they get the correct answer. If you tag them and they think they have the right answer, they...

## Math Addition Activity – 4

I made these cards up — I think there is an official name for them like math wraps or something. Someone described them once and so this is what I came up with. Please like & share:

Here’s yet another activity LD uses for practicing addition…it’s called an addition strip board and I printed it out for free from here: http://www.montessorimaterials.org/Math/AdditionStripBoard.pdf You’re supposed to take a blue number and a red number, place them on the board and find the sum.

## Math Addition Activities – 6

We played “War” with some addition cards we had on hand. Whoever has the highest sum wins the round. Please like & share:

## Math Addition Activities – 7

I’m not sure this exactly qualifies as addition (it’s also logic, strategy and so forth), but LD got this award winning card game for his birthday and LOVES it. It is called Rat-a-tat-Cat The premise is that you have to get rid of your rats (the high cards like 7, 8, 9) and try to get only low cards. You can not look at your face down card unless you...

## Copy Me — Preschool Symmetry Activity

To introduce the concept of symmetry to my preschoolerwe played the “copy me game.” (That’s what I called it.)First I put down an object and she had to put one in it’smirror image (I showed her how if I folded the paper overit would be right in that spot where the paper touchedon the other side.) Then she had to put down an objectand I had to copy her. We...
