Does anyone else have students in their class who keep forgetting that a number family meets that only those 3 numbers in that number family can be included? My kids were really struggling with this, so I put together these houses as a quick, last minute activity right before winter break. There are number tiles that the students cut and paste to make the equations that are in the number family. It’s a simple, easy activity, and if you click on the picture, you can grab a copy FREE from google docs, simply click on either of the pictures above. I only have the one fact family, but it’s very easy to change the activity by simply changing the numbers in each box. Feel free to alter at will! And take advantage of that, because it’s rare to hear it out of me!
That’s all I have today folks, short and sweet (for once!). Hope everyone’s having a good week back to work. BTW – If you haven’t seen my New Year’s Center Packet yet, it’s not too late to grab it!
My students were having a bit of trouble understanding the difference between addition and subtraction. We did a variety of activities to help them understand, including using manipulatives, pictures, and putting two equations with the same numbers, but different signs right next to each other (5+3=8 5-3=2). However, the thing that worked the very best was to let them come up with their own word problems. At first, they were just excited to be able to use each other’s names, but as they got to drawing, they really understood all of a sudden that in addition you have two separate groups, where as in subtraction you have one group and you are giving some away. It’s also made my problem solving center run so much smoother! Here’s what we did:
1st – We wrote an addition word problem using the names of our friends. We also drew a picture to represent our word problem.
2nd – On the back, we wrote the addition fact that would solve the word problem we created.
3rd – We had each student’s page bound into a book and placed it on the “warm shelf” to be read over and over.
4th – Repeat Steps 1-3, with a subtraction fact.
5th – Had a whole class discussion about the difference between addition and subtraction.
