Here is what we are working on in Horizons extension classes.

**School year 2016-2017:**

**3rd Grade Science/Social Studies Extension class:**

Students who qualify for Science / Social studies extension class meet in the Horizons classroom once a week for 45 minutes to 1 hour.

Students participate in Inquiry based thematic units covering such topics as:

*Maine state geography, economy, industry, regions, animals, plants, historical figures, authors, farming, food, climate, architecture, and much more.

*Geometric structures and Origami

*Robotics and programming/coding

**3rd Grade Math Extension class:**

Students who qualify for Math extension class meet in the Horizons classroom once a week for 45 minutes to 1 hour.

Students work following a workshop model. They rotate through stations that include:

1 station of independent work at their instructional level

1 station of math games

1 station of math apps on the ipads

*I begin each class with a math lesson and then students are directed to a work station and we begin rotating. I rapidly move from station to station and student to student, offering instruction, guidance, and doing formative assessments.

Some examples of math games and challenges:

Students attempted to 'guess my number' in 4 or less guesses, using questions involving: prime numbers, square numbers, divisibility rules, and combined questions. They had to work very hard at being respectful listners, not interrupting each other (and me), finding consensus on whose idea/question would eliminate the most numbers, and strategies. They were able to guess my number (between 1 and 100) in 6 steps/guesses!

The 24 Game: (using order of operations, multiplication, division, addition, subtraction)

Guess My Number: (even, odd, prime, composite, and square numbers) Guess the Number

Rullo: (on the ipad: game of strategy, creative thinking, and addition)

Math Marathon challenges: using measuring tools to calculate Area, estimation of height, observation of geometry in our learning space, and much more.

The Year Game: order of operations and dabbling in the use of factorials and sigma

Kings Digits Game: (similar to The Year Game).

Continental Math League challenges (CML): word problems involving a variety of math skills

Divisibility Challenges: (learning all divisibility rules from 1-11 and a focus on place value, multiplication and division)

Here is an example of one :

Here is an example of a typical 3rd grade level *CML* question:

*There were 325 people at a conference. If each of 30 people brought 3 guests, each of 20 people brought 2 guests and each of 40 people brought 1 guest, how many people did not bring any guests?*

Here are examples of a typical Marathon Challenge problem (hands-on math):

*Which two place values have the shortest names?*

* Use a calculator: If it's the year 2014, how many more years would go by before all 4 digits will be the same?*

* Find one object in the classroom that has a very long width, a very long length, but a very short height. What are its dimensions? What geometric shape is it?*

**3rd Grade Reading Extension class:**

Students who qualify for Reading extension class meet in the Horizons classroom once a week for 45 minutes to 1 hour.

Students read both fictional chapter books and also informational text such as articles from the Tuesday New York Times Science section.

**4th Grade Science/Social Studies Extension class:**

Students who qualify for Science / Social studies extension class meet in the Horizons classroom once a week for 45 minutes to 1 hour.

Students participate in Inquiry based thematic units covering such topics as:

*Geography and landforms, topographic map making, erosion stream-table experiments, geo caching

*Solar Energy, using solar ovens for cooking, building solar houses, the Sun's heat vs photovoltaic cells

*Robotics and Programming/Coding

****A big thank you to the Meil family for donating 3 more small rolling sphere robots. It will be fun to see how we can incorporate them into our programming unit.*

****I continue to be incredibly grateful to one generous third grader who chose to spend his own, saved money to buy a second Dash robot (and a xylophone for Dash) for the Horizons program to use, so that more students can be programming and enjoying hands-on learning, at one time. We've (the third graders and the kind student who donated the robot) named that robot after his benefactor. This 'Dash' robot in now nicknamed Wally. :)*

If a student is interested in learning more about coding and programming at home, he/she can explore:

**4th Grade Math Extension class:**

Students who qualify for Math extension class meet in the Horizons classroom once a week for 45 minutes to 1 hour.

Students work following a workshop model. They rotate through stations that include:

1 station of independent work at their instructional level

1 station of math games

1 station of math apps on the ipads

Students worked on origami 3-D manipulative shapes called flextangles and played memory games.

- Every week, 4th grade students will work on independent challenges such as solving divisibility puzzles (see above example in the 3rd grade section), while also having the opportunity to work in small groups or pairs playing math games. They will practice not only doing the computation, but also showing their work and explaining (in writing) how they solved problems.

Some of the weekly math challenges students have worked on are:

The 24 Game: (using order of operations, multiplication, division, addition, subtraction)

Guess My Number: (even, odd, prime, composite, and square numbers) Guess the Number

Rullo: (on the ipad: game of strategy, creative thinking, and addition)

Math Marathon challenges: using measuring tools to calculate Area, estimation of height, observation of geometry in our learning space, and much more.

The Year Game: order of operations and dabbling in the use of factorials and sigma

Kings Digits Game: (similar to The Year Game).

Continental Math League challenges (CML)

Divisibility Challenges: (learning all divisibility rules from 1-11)

****These are the same types of challenges that are offered to 3rd graders, but I require additional proof of solutions or I add more challenging twists to those offered to 4th graders.*

Here is an example of a typical word problem:

*Hillary's weight on the planet Jupiter is 7 times her weight on the planet Mercury. Her weight on Earth is 3 times her weight on Mercury. If her weight on the planet Jupiter is 210 pounds, how many pounds does she weigh her on Earth?*

Here are examples of a typical Marathon Challenge problem (hands-on math):

* Subtract the number of faces on a dodecahedron from the number of rooms in The White House (hint: use a reference source to find out more information). *

* 6336 is a number palindrome (a number that is the same forwards and backwards). Subtract the year that was 20 years before the current year, from 6336. What does that equal?*

* Look in your math reference book's glossary. Find the words that begin with "A". How many are there? Write down all the multiples of that number that are below 100.*

**4th grade students who work on divisibility puzzle challenges (see example above) are required to show all the divisibility rules and actual math used to prove or disprove each divisibility clue.*

**4th Grade Reading Extension class:**

Students who qualify for Reading extension class meet in the Horizons classroom once a week for 45 minutes to 1 hour.

Students read both fictional chapter books and also informational text such as articles from the Tuesday New York Times Science section.

*Reading class lessons incorporate challenges that align to 4th grade reading and writing standards.

We continue to work on Red Herring puzzles (noticing the importance of word choice when writing a puzzle meant to throw a person off). Below is a Red Herring we will work on. Ask your 3rd or 4th grader to let you try and solve it (remember, you can only ask questions to which the answer is yes or now):

*One afternoon, while camping with her family, Bev was asked to go to the river and bring back a bucket full of water.*

*To her surprise, the only bucket she could find had several large holes in its bottom.*

*Undismayed, Bev managed to fulfill the request. How did she do it?*

If you want to enjoy another really fun mystery word game, ask your 3rd or 4th grader to explain how W.A.I.T.O. is played and let them come up with the first word for you. Gist of the rules: the word has to be a noun, can't be plural, can't be a compound word, can't be a proper name. you begin by sharing the first letter only. Someone comes up with a word, the rest try to guess it.

Example: if the mystery word is COW. You would write C_____

To make a guess you can't come right out and ask, "Is it a car?". You would have to ask, "Is it a vehicle that has 4 wheels and people drive them?" The person who thought of the word must then respond with whatever they assume you are guessing. Maybe they'd say, "No, it is not a car." Then, you might ask, "Is it a cute, furry creature with whiskers?" (think cat) You might say, "No, it is not a cat." or you might be mistaken and say, "Yes it is a COW!" (only if you happen to of cows as cute and furry with whiskers. :) That's the gist of it. Your 3rd or 4th grader can help with the rest.

***In addition to Extension classes, students who are 1 or more grade levels ahead of their grade level, in math, can be nominated to be screened for accelerated math classes. There are specific time windows in which nominations and screeings for accelerated math classes can take place. **

**Please see the descriptions of programming and screening on the Horizons page that brought you to this online newsletter page, to answer any questions you might have.**

***The Horizons teacher also provides classroom teachers, in grades k-4, differentiation resoures / materials and guidance in creating differentiated challenges and extensions for lessons.**
