Solutions

Okay, sorry it has been a while since I updated our exciting science experiments.  We created solutions.  First we determined that solutions dissolve much faster in hot water instead of cold water.  Then we tested a race to dissolve.  Which dissolves faster: sugar cube or granual?  Well, the granuals won.  The definition to solution is a mixture that can not easily be separated.  So, we tested that as well!  Can sugar and water be separated after it has been mixed together?  The result was YES!  We evaporated all the water and the sugar started to cook on the bottom of the beaker.  It was pretty cool!

3 Ways to Multiply

Today we practiced and practiced, and practiced some more.  Each student chose for themselves which of the three methods was easiest for them.  Check out our poster!

2 Digit x 2 Digit

There are several ways to find a product.  We learned 2 ways today; traditional and partial product. 
For the traditional method, I taught the students to say "OZTA" which stands for Ones, Zero, Tens, Add.  It helps them to not get lost in the process.
For partial product, the students write each number in expanded form and then multiply and then add the products.  They are taking the number apart and then putting it back together. 

Multiplying Across Zeros

We got this!  We completed a journal entry on how to multiply across zeros today.  It will be our easiest multiplication lesson ever.  We even got to prove it on a calculator!  Check it out! Find the basic factors and multiply then add the zeros to the end.

What do you want me to do???????

How do I know when to add or subtract?  Oh, those word problems.  Questions in Math have changed over the years.  No longer are there "Key Words" like altogther, total, each, separate, etc.  The key words have been removed and the students have to recognize real world situations.  Therefore, we made a poster to help identify situations.  When this happens in the story, we will . . . . .  Check out our poster!

Heshima!

Heshima won last week's House Rally!  Who will win tomorrow?  Bring in batteries to help your team.

Which will float?

Today we completed our final mixture; woodchips, pebbles, and water.  We predicted which solid would float and then combined our mixture.  We stirred it up and allowed it to settle. Then we observed at eye level to determine which solid would sink and which would float.  The pebbles are more dense than the water, so they sank.  The woodchips were less dense, so they float.  We got our hands wet separating the mixture back to its original form. 

Multiplication Chart

Today we made the X chart SOOOOO much easier.  We did what we KNOW for a fact: 0, 1, 2, 5, 10, 11 in orange.  Wow!  Look how much of the chart is complete.  Now we went down the middle with prime numbers. EX: 0 x 0, 1 x 1, 2 x 2.  Then we highlighted the factor on bottom in yellow and crossed off its communicative property on top.  EX: 3 x 6 = 18 so 6 x 3 = 18.  We really only need to know less than half of the chart!
