# Category Archives: Subtraction

Here is a quick and simple idea I’ve been using to help my kiddos who are struggling with writing addition and subtraction equations:
I gave each of them 10 of a different color of cubes (but you could use anything!).  I asked them to show me a particular math sentence, first with cubes and then to write an equation for it.  They picked up pretty quickly, now we will just review everyday, until I’m sure they understand. 🙂
How do you practice addition and subtraction with your kiddos?  What materials do you use?

## February Problem Solving

It’s here!  I had lots of requests for a February Problem Solving pack after I shared the one I created in January.  You can click the picture below to get yours. 🙂

This pack contains 25 problem solving activities that cover subtraction, measurement (length/comparing lengths), and decomposing numbers…the three big standard strands I’ll be covering in February! 🙂

The specific CCSS that are covered for Math are: K.OA.1, K.OA.2, K.OA.3, K.OA.4, K.OA.5, K.NBT.1, K.MD.1, and K.MD.2.

There are three basic sheets that are included in this pack and you can see them on the picture above.  This pack does require cutting, so make sure you have scissors available. 🙂

## iSpy bags

I’m hooked!  On Pinetrest that is!  I found this idea a few days ago and had the materials (mostly) laying around.

I found this great tutorial here and l decided that because I had most of the materials already laying around, I could make some of these.  I went to Jo-Ann’s and looked for things that were small: beads, rhinestones, buttons, etc., that would fit inside one of these bags.  I also purchased two 32 oz. bags of plastic pellets, used to fill up dolls/children’s toys.  I have made 13 so far (they are not all pictured).  I also purchased some bags of trinkets from a store on etsy. (LOVE etsy!)

The items you see laying on the white paper will eventually be printed off, laminated, and attached with grommets so that the children can use a dry erase marker to circle the items that they have found.

Wouldn’t these be great with magnetic items inside as well? 🙂  For the bag with the numbers, I was thinking it would be great addition and subtraction practice for the children to find a number, then roll a die to see if they would add or subtract the next number they find!  You could do all kinds of things with these!  Use them in Work Stations, make them easy or difficult…how about putting sight words in them and letting the children write them as they find them?  How about printing the words in tiny font and using a magnifying glass to read them and then say them out loud?  The alphabet bags could be used to spell words…the ideas are endless…do you have any other ideas?  Leave them in a comment here! 🙂

I am thinking of making some to sell.  I made mine so that they correlate to units or themes we are working on in our IB units.  So far, I’ve got one for ponds, letters, numbers, recycling, gingerbread men/women, animals, pets, and a few just for fun ones!

Let me know if you might be interested in purchasing one or two…I’m thinking \$10 for each one, with laminated tag included and attached. 🙂

## New Math Work Stations

Here are some more pictures of our newest Math Work Stations.  We’ve moved on to the 3rd quarter Math Common Core Standards (mainly addition and subtraction and 3D shapes).  I’ve introduced a new puzzle that helps with addition and subtraction, some games about weight (heaviest/lightest), and a dramatic version of 5 Green and Speckled frogs to help with the idea of subtraction.
