1) Double digit x double digit side (5- 10 problems using standard algorithm)
or
2) Flip side with double multiple x single digit (10 problems using standard algorithm)
or
3) Both sides choose 5 from each and okay to use Lattice for double digit x double digit.
5th Grade Math - packet
Homework - Vocabulary/Wordly Wise: Friday is a review test of lessons 5 & 6 in Wordly Wise. The students are making flash cards to use to practice at home to learn the meaning and usage of a select group of words from the lessons. Each student has the review sheet for their book, with the bold printed words being the ones we expect them to know (They will also select more words of their own choice to practice). On the "test" the students will have the words provided for spelling purposes, but be required to write the meaning and a sentence using the word.
4th Grade Math: Today reviewed multiplication, practicing facts, mental calculations and use of algorithms. We introduced the standard algorithm for double digit x double digit problems. Previously the students not familiar with this algorithm were using Lattice for larger problems, and the standard only for problems with single digit factors. Our goal is for students to become familiar with both techniques and settle on the method that works. We will begin a new focus on geometry in the coming days.
Math Club with Sima - We kicked off the New Year in Math Club with Magic Squares and the Circle Down solitaire game. Many students were absorbed in figuring out the proper moves in the checkers-like Circle Down game to remove all but one counter. Others tried to place the digits 1-9 in a Magic Square that had all of its horizontal, diagonal, and vertical rows add up to the same number, and some took it further to investigate larger Magic Squares. Finally, we looked at an interesting Brain Teaser requiring students to figure out the cost of each letter given the cost of 29 different names. If you succeed in figuring out the cost of your own name, you can check your answer online here.
Bully Talk with Kate and Hillary: Kate and Hillary visited today to begin a conversation with Strawberry that is happening school wide about "bullying." Kate brought her chickens along to illustrate bullying in form of a pecking order. The kids brainstormed what behaviors they associate with teasing/bullying and ended the activity with a journal writing exercise about their experiences with bullying. (Photos below)
Ideas for families (from Sima) related to Marine Sciences:
On Saturday, Jan. 12 at 3pm, explore tide pools at the Marine Sciences Institute in Redwood City on a Lowtide Walk. MSI takes
to the tidepools for a treasure hunt of nature's beautiful intertidal
secrets. We'll spend the evening taking advantage of the low tide to
reach the outer edges of Pillar Point, and take in spectacular sunsets
as we slowly retreat to shore. Will we find crabs, sea stars, eels and
octopus!? This is a great all-ages, family event
On Sunday, January 13 at noon or 2pm, visit The Marine Mammal Center in Marin for a FREE FAMILY day of fun, learning about the inhabitants of the arctic! Find out how walruses, narwhals and whales survive freezing temperatures. Docent-led tours are available as well for a nominal fee.
Saturday, Jan. 19 is the 22nd anniversary of the sea lions returning to PIER 39 in San Francisco. Activities are scheduled each day between Jan. 19 - 22 and include free educational tours by The Marine Mammal Center and the Aquarium of the Bay.
