Nature Study: Bioluminescence

Have your kids ever seen pictures of glowing jellyfish , fireflies lighting up a summer night, or deep-sea creatures that shimmer in the dark? That magical glow is something called bioluminescence —and it’s one of nature’s most fascinating light shows! Angler Fish craft My class recently participated in a STEM workshop where they learned about bioluminescence in the deep sea. They learned about deep sea creatures like the Angler fish and how bioluminescence was part of their adaptation to the dark depths. They also had a blast making their own Angler fish complete with antennaes. Coincidentally, on this day we got to the chapters in ' The Wild Robot Escapes ' where Roz the robot was exploring the deep ocean and learning about bioluminescence, echolocation and the predatory nature of seabirds like the Skuas . (That's for another blog post!) For children, learning about bioluminescence offers an incredible way to bring science, nature, and imagination together. It’s a to...

🧠 Mental Math: Helping Kids Manipulate Numbers in Their Mind

Is a Math Problem an Imagination Problem? 

When we think of math, many people imagine strict rules, memorized facts, and endless worksheets. But for kids (especially in the elementary years), math is much more like a journey through the imagination. It’s about being able to picture numbers in your head, play with them, and move them around like puzzle pieces.


For children, developing this skill is called mental math, and it’s one of the most powerful tools they can carry into middle school, high school, and adulthood.


Why Math is an Imagination Problem

Numbers aren’t just symbols on a paper, they represent ideas. When a child sees “7 + 5,” the challenge isn’t just adding digits. It’s about imagining seven things, five things, and then combining them into a whole. The stronger a child’s imagination for numbers, the easier math becomes.


Think of math as a playground in the mind:


➕️➖️Addition and subtraction are like stacking and removing blocks.


✖️Multiplication is making groups of the same size.


➗️Division is sharing fairly.


When kids can see these actions in their imagination, they don’t just memorize facts, they understand them.


How Parents Can Help Kids Imagine Numbers


Spectrum Hands On
Workbook
1. Use Real Objects First

Before kids can move numbers around in their mind, they need hands-on experience. Use apples, toy cars, or Legos to act out problems. Once they get the idea physically, ask them to “try it in their head.”


For Example: “If you had 8 Legos and gave me 3, how many would be left? Can you picture it without moving them?”

2. Encourage Visual Thinking

Ask your child to see numbers in pictures. Some kids imagine number lines, others see groups, and some even see colors or shapes.


For Example: “Close your eyes. Can you picture 10 cookies on a plate? If we eat 4, how many are left? What does it look like now?”

3. Teach Friendly Numbers

Show kids how to make problems easier by imagining friendlier numbers.


9 + 6 → “Think of 10 + 5.”


25 + 19 → “Think of 25 + 20, then subtract 1.”


This trick builds flexibility, a key to strong mental math.


4. Play Mental Math Games


Make number imagination fun: “What’s Missing?” Say a number and ask what needs to be added to reach a goal (e.g., “What do I add to 37 to make 50?”).


Number Stories: “There are 15 birds in a tree. 7 fly away. What does the tree look like now?”


Beat the Clock: Give a problem and let your child solve it in their head before writing it down.


5. Normalize Thinking Time

Mental math takes patience. Kids may pause, frown, or use their fingers. That’s okay. Celebrate the process, not just the answer. 

Remind them: Good thinkers take their time.


Take Away

Math isn’t just about getting the right answer, it’s about training the imagination to see numbers in different ways. By helping kids picture numbers in their minds, we give them the confidence to approach math not as a chore, but as a creative challenge.


After all, when math becomes an imagination problem, kids begin to realize: they already have the tools to solve it!
