Math Centers

We have been working extremely hard in class 403,  we finish our week with Math Centers.

I was very excited about my math centers for three reasons #1- I can meet with small groups more frequently and efficiently, #2 they help the students round out their math learning with lots of active practice #3 I love my math centers and am proud to show them off and share them with my kids!  They really enjoyed themselves too; they didn't know they were actually working really hard:)

We took advantage of the beautiful weather by taking our work to the park!  What a beautiful day!

Have a wonderful week-end!

What's happening in class 403

We have been soooo busy this week!  We've been working on our Daily 5/5 au Quotidien and tomorrow we will be working with Math Centers.

Adamo is hiding under a desk!

Have a great week-end!

La classification des animaux et leur reproduction

Nous sommes en train d'apprendre des choses tres interessantes sur les animaux.
Hier en classe nous avons vu deux videos sur la reproductions des animaux.
Il y a des animaux ovipares. Un animal ovipare est un animal qui pond des oeufs et dont la croissance de l'embryon ce déroule dans ce dernier.  C'est la femelle qui pond un œuf, puis le développement de l'embryon, le futur petit, se fait dans cet œuf, en dehors du corps de la femelle.

le developpement d'un animal ovipare: un poussin.

le developpement d'un animal ovipare: une grenouille

Il y a des animaux vivipares.  Une espece animale est dite vivipare lorsque l’embryon issu de la fecondation  se développe à l’intérieur de la mère, au sein de l'uterus.  Elle se charge donc de le nourrir au moins jusqu’à son expulsion. Chez les placentaires, la nourriture est transmise via le placenta et le cordon ombilical. La viviparité est présente chez tous les mammiferes, à l'exception de l'ornithorynque et des échidnés.

Le developpement d'un animal vivipare: un chiot

Il y a des animaux ovovivipares. Les animaux ovovivipares eux, sont un peu un mélange des deux modes, le temps du développement de l'embryon. Après l'accouplement, la femelle produit des oeufs, mais elle ne les ponds pas, ou, comme pour l'hippocampe (seahorse), elle les transferts au mâle qui les porte dans une poche ventrale. Le développement des embryons se fait comme pour l'oeuf d'un oiseau. La nutrition n'est donc pas produite par la mère, ou le mâle, étant contenue dans l'oeuf.
Les discussions en classe étaient vraiment interessantes:)

Rounding

Rounding means reducing the digits in a number while trying to keep its value similar.  The result is less accurate, but easier to use.

Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80.

The method we use in class 403
There are several different methods for rounding,  but in class 403 we will use the rounding rollercoaster:)
How to Round Numbers?
Decide which is the last digit to keep.
Leave it the same if the next digit is less than 5 (this is called rounding down) But increase it by 1 if the next digit is 5 or more (this is called rounding up)

Example: Round 74 to the nearest 10
We want to keep the "7" as it is in the 10s position
The next digit is "4" which is less than 5, so no change is needed to "7"
Answer: 70=74 gets "rounded down"

Example: Round 86 to the nearest 10
We want to keep the "8"
The next digit is "6" which is 5 or more, so increase the "8" by 1 to "9"

Answer: 90=86 gets "rounded up"

We watched a video today by Khan Academy and worked on our ISN.

Welcome to grade 4

Welcome to grade 4!
We had our welcoming activity on Monday last week.  The games for so much fun!

Working in class...

What will our teacher post next?

A brand new year!

Hi!  I’m Miss Lopez!

Teaching is an absolute passion of mine!  I am so excited to work with you and your child!  It is going to be a year full of fun, learning, and lots of adventures.  I can’t wait to see what the year has in store for us!

Today during our math lesson we reviewed place value.  We are doing a great deal of review these first weeks, just to refresh our little minds:)
 Click here to get a closer look of the video we watched before we tackled the pages of our Numbers workbook!
