Day 129

For one year, 365 days, this blog will address the Common Core Standards from the perspective of creating an alternate, ambient learning environment for math. Ambient is defined as “existing or present on all sides, an all-encompassing atmosphere.” And ambient music is defined as: “Quiet and relaxing with melodies that repeat many times.

Why ambient? A math teaching style that’s whole and all encompassing, with themes that repeat many times through the years, is most likely to be effective and successful. Today’s post will feature the next Grade 2 Common Core Math Standard listed in blue, followed by its ambient counterpart as practiced by Waldorf Education and Math By Hand.

Operations and Algebraic Thinking 2.OA

Work with equal groups of objects to gain foundations for multiplication.

4. Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.

This was covered repeatedly in Grade 1, and is reviewed at the beginning of Grade 2. It’s used most effectively when comparing addition and multiplication. This is another good reason why all 4 processes should be taught at once, from the beginning. If there’s no need to build a foundation for multiplication now in Grade 2, more advanced concepts in multiplication that are related to the above standard can be explored.

In the Waldorf and Math By Hand Grade 2 curriculum, fables are used to teach and practice math concepts. Fables lend themselves beautifully to this purpose. In order to elaborate fully on this relationship, I will devote tomorrow’s post to it. Pairing the following fable with the square numbers up to 25 is a concept that is somewhat related to the above standard. Having worked with the 5’s table since the beginning of Grade 1, it’s appropriate to now interpret this standard along these lines.

Here is a fable, followed by instructions and a drawing for applying it to the square numbers up to 25.

**The Lion and the Mouse**

A Lion lay asleep in the forest, his great head resting on his paws. A timid little Mouse came upon him unexpectedly, and in her fright and haste to get away, ran across the Lion’s nose. Roused from his nap, the Lion laid his huge paw angrily on the tiny creature to kill her.

“Spare me!” begged the poor Mouse. “Please let me go and some day I will surely repay you.”

The Lion was much amused to think that a Mouse could ever help him. But he was generous and finally let the Mouse go.

Some days later, while stalking his prey in the forest, the Lion was caught in the toils of a hunter’s net. Unable to free himself, he filled the forest with his angry roaring. The Mouse knew the voice and quickly found the Lion struggling in the net. Running to one of the great ropes that bound him, she gnawed it until it parted, and soon the Lion was free.

“You laughed when I said I would repay you,” said the Mouse. “Now you see that even a Mouse can help a Lion.”

A kindness is never wasted.

**The Square Numbers Up to 5 / 25 and the Mouse
**

**1)**Lay out the pattern with dots first. These can be the knots in the net.

**2) **Add the lines between the dots to create the squares, erasing in spots and adding the gnawed places.

**3)** Write all the counting numbers in lightly, darkening the “X” numbers, with the square number on the bottom right. Write the equation next to each one.

**4)** Create one more 5 square with all the square numbers in different colors inside. Title the drawing and add our hero the Mouse!

Knowledge ensues in an environment dedicated to imaginative, creative knowing, where student and teacher alike surrender to the ensuing of knowledge as a worthy goal. Tune in tomorrow for more Common Core, along with its ambient, Waldorf/Math By Hand counterpart.
