Math Twister

Here's a fun Math game you can make at home, suggested by "The Inadvertent Farmer"...(click image, below). It involves using the whole body in finding combinations of 10. Besides the Math benefits, this activity includes motor coordination, balance, visual discrimination, concentration, cooperation, and FUN!

PLEASE NOTE: Before introducing this game, make sure the child recognizes and has a concrete understanding of the numerical symbols, 1-10. Plus, provide a demonstration on how to make combinations of ten with concrete manipulatives. Examples: the Montessori Golden Beads, Addition Strip Board, Snake Game beads, colored Math Beads... 

Enjoy!

Math & The Isolation of Stimulus

Alexandra Sanna, UMA student from Rome, Italy, shares her original Math project. Come follow us on this wonderful Montessori journey of discovery and transformation with us!  

Photo #1:

  

  • Above (#1)...A plastic tray to hold the materials, a basket to hold the colored beads - 1 red, 2 green, 3 orange, 4 yellow, 5 blue, and a cardboard box to hold five colored block with dowels - red, green, orange, yellow, blue

Suggested changes: Provide a non-plastic tray (natural materials always preferred), non-cardboard box (needs to be sturdier material), reverse position of basket and box (so movement is L to R).   

Photo #2:

  • Above (#2)...Colored blocks are arranged in "numerical" order with the goal of matching the color of the bead(s) to the blocks. The number cards are placed underneath and, as a "control of error," turned over to reveal the matching bead color.

Suggested changes: Make a stand to hold the blocks in place. Rotate the cards so that the dots are vertical, rather than horizontal for visual accuracy. 

IMPORTANT - ISOLATION OF STIMULUS

(1) The main purpose of this Math activity is to determine the sequence of quantity (1-5), rather than match the colors. Although the different colors allow for an additional "control of error," it is better to make all the colors the same.

(2) The beads are different shapes. Make them all the same, again, for visual accuracy when viewing the quantities side by side.

 Photo #3: 

  • Above (#3)...The plastic tray has been removed, the colored blocks with dowels have been replaced with a natural colored wooden stand without color coding, and the colored, multi-shaped beads are now all the same (blue and round).

Photo #4:

  •  Above (#4)...How visually appealing and easy to see the increase of quantity in equal increments, due to the isolation of stimulus. On the back of the dotted cards, there are corresponding numerals. Either side may be used, depending upon the age and ability of the child. 

Suggestion: Line up the dots on the cards in single verticle rows to match the beads on the dowels, rather than by two's. 

------------

Alexandra Sanna, per our suggestion, did not let the original project go to waste! She has made a color-matching exercise with an equal number of beads on each color-coded dowel on its color-coded stand. This is now on her Sensorial shelf.

Thank you, Alexandra, for sharing your journey with the Montessori community. Beautiful job!

The GIANT Number Roll

Jeanna Harris, UMA graduate and teacher at Cottage Montessori School in Silverdale, WA shares these amazing photos of a young boy's dedication to the Montessori Number Roll.

Meet 6-year-old Gabe Carpenter! 

"Highest any of my students have ever gotten...11,000!"

"It took him about 16 months total. We have had him in our classroom for 2 years, and now he is graduating!"

"Gabe is so motivated. Whatever he does, he gives 100%."

Way to go, Gabe! We'd all love to see what you're doing 20 years from now!

A Tooth Graph

Here's an idea for the whole classroom to participate in: A Tooth Graph

Write the number of teeth lost on the left and the names of the months along the bottom.

Math - Fractions Booklet

Here's another idea taken from the 2011 PNMA Montessori Spring Sharing Fair in the Seattle area. It's self explanatory, so follow along with the photos. Enjoy! 

Use the laminated booklet (above) as a "control" and allow the child can construct his/her own individual "Fractions Booklet." We recommend using all one color (below), keeping "isolation of stimulus" in mind.

Free Download: Star & Number

One of the many benefits of UMA Membership is being able to enjoy "freebies" for home or classroom use. UMA membership is free, so sign up and download the latest Math worksheet entitled Star/Numbers... a very simple tracing & counting exercise. Notice how the odd and even numbers are easily differentiated.

REMEMBER!  Rather than individual worksheets, we encourage that you laminate the document onto heavy cardstock and allow the children to use a dry-erase marker, to be used over again many times!

Math, Sandpaper Numerals with Dominic, part 3

Okay, here is part 3 of the impromptu demonstration with our little friend Dominic. You can view part 1 here. Remember, this was done "on the fly" and the first time Dominic had encountered a Montessori Math lesson. The video quality is diminished.

Math: Original Project

A fun activity for classroom or home!

May Brymn from Silver Spring Maryland shares her Math original project for UMA. She uses all natural materials...wood tray and glass candle holders. Very inviting!
