Patterns/Subtractions/Fractions Oh My

Yeah! A wonderful teacher told me today that she was recently reading my ramblings. I had stopped writing because I was getting discouraged about my lack of an audience so it's great to hear that at least one person reads this! So without further ado here is what I did today... I spent the day in one of our amazing schools in a variety of different grades.

My first stop was in a Kindergarten classroom. We learned about AB patterns, AABB patterns, AAB patterns and ABB patterns. What a busy day for all those K students. We started off the day on the carpet with a short story. Within the story was an AABB pattern. Students quickly recognized it and I asked them to build a similar pattern using snap cubes. They did.

Then we moved back to the desks and played musical patterns. Students had to use 5 snap cubes or pattern blocks to design an AABB pattern. Once they had the first 5 pieces, I turned on the music and they started to dance around. When the music stopped, students moved to a nearby desk and had to add 2 pieces to the pattern displayed. They loved being able to move around and I loved having that quick visual check of how much they understood/didn't understand.

We did the same activity where we looked at the pattern, and then played musical patterns again with each of the other 3 patterns.

Finally, I handed out iPads and asked students to use Educreations to take a picture of a pattern they designed and record over it with their voice to explain which pattern it was. They did wonderful and I was so pleased with the diversity of their patterns.

There are another couple of great pattern apps that we downloaded for the students to use later this week.

Next up I went to a grade 1 classroom. We were working on subtraction. I started off with this Shark Teeth Activity I found online to help see what the students already knew as well as give them some basic manipulatives to help demonstrate their understanding.

Next we moved on to using a clothesline of numbers to demonstrate being able to count on a number line. I hung clothespins on numbers from the ceiling (a bad idea as it was too high for the students and I ended up having to hold them up!). Then I asked the students to move the clothespins down the number line as we subtracted.

We next applied this concept to this Number line subtraction game I found online. I modified it slightly by using clothespins instead of counters. Students each put their clothespin on the 20. Then they rolled a die and moved their clothespin down the number line. I asked students to verbalize their thinking (20 subtract 4 equals 16).

Finally, we applied this concept to a hundreds chart and played Off the Grid by Mama Jenn (I LOVE this game).
