# Half-Hearts for Mother’s Day

## The Activities

1. Topic: Addition: Book: Monster Math Picnic by G. Maccarone.
2. Topics: Numbers, Counting: I gave the kids a big pile of unit cubes from our Base Ten Blocks (about 125) and asked them to count the total.
3. Topic: Patterns: We made copies of Lessons 33 and 35 from Lollipop Logic, Book 2 which asked the kids to say what the next shape was in a simple repeating pattern.
4. Topic: Graphs: We made printouts of a grid with letters on each row and numbers on each column.  Then, we have a series of coordinates (e.g., A9) along with what color to color that square.  When you’ve colored all the squares as indicated, you get a picture.  You can download this activity here.
5. Topics: Geometry, Symmetry: Book: Let’s Fly a Kite by S. Murphy.
6. Topics: Geometry, Symmetry: I showed the kids how to make symmetric shapes by folding a piece of construction paper and then cutting out “half” the shape.  E.g., to make a kite you cut out a triangle along the fold line.  Then I gave them some challenges, such as “make a square”, and ended with “make a heart” for Mother’s Day.

## How Did It Go?

We had 4 kids this week.

#### Monster Math Picnic

A simple book about different ways to divide 10 into two groups.

#### Counting Blue Blocks

They didn’t have any good ideas of how to start; a couple of the kids started trying to count one-by-one, but gave up around 30.  After a bit I suggested they should make piles of 10, which they all did.  After we had everything grouped into 10’s, they still didn’t quite know what to do, but once I started counting by 10’s, they caught on, and one of the kids added on the last 5 to get the right answer.

#### Lollipop Logic

This activity was pretty easy for all of them.  The main difficulty was concentrating on the activity instead of getting distracted.

#### Letter-Number Pictures

This one was a bit tricky, but all of them got the idea of finding the right square after a while.  They chose the right square a good fraction of the time.  Interestingly, the hardest thing seemed to be getting into the rhythm of finding the next coordinate pair, finding the square, coloring, finding the next, etc.  For many of the kids, when I helped them find the next coordinates, they could then color the square without help; but then they would just sit there and not move on to the next coordinates.  One of the kids was much more successful than the others and quickly finished the starting picture plus another 1.5 pictures; most of the kids only finished the starting picture plus half of another picture.  I think that the kids didn’t fully realize that they were going to get a picture once they were done, or else this just wasn’t that motivating to them for whatever reason.

#### Let’s Fly a Kite

This book had a bunch of nice examples of symmetry set inside a story about a babysitter and two arguing kids (who always wanted things to be fair).

#### Cutting Symmetric Shapes

The most interesting thing that happened in this activity was that when I asked the kids to make a square, they all ended up with a 2×1 rectangle, because they cut out a full square instead of a half square.  Making a heart was pretty tricky for them.  I let the kids have a while to cut whatever they wanted, so we got some interesting shapes.
