Imagine you're sitting at a table. In front of you is a big handful of blueberries. Just scattered around. Blue, round, delicious. You need to count them. Quite tricky, right? The blueberries are all over the place. Some are stacked on top of each other, others roll away. You start counting. "One, two, three... Wait, did I count that one already?" And back to the start. "One, two..." Oh dear. That's the problem. When things are messy or unstructured, it's hard to see the exact number. This isn't just true for blueberries. But there's a trick. You can count better with your eyes when your brain recognizes an order. If you sort the blueberries into small groups. For example, always 5 or 10 pieces, then your brain can calculate much faster.

How it works

Get yourself a portion of blueberries. Place them in a bowl or on a plate. Don't eat them! Not yet. First, count.
Take a good look at the pile. Take your time. Count as best as you can. You'll notice: It's not that easy. The berries all look similar. You might lose track. That's okay; that's exactly the point. You should feel how hard it is when there's no order.
Now comes the trick. Group 5 berries together. Look at your work. Now your brain sees: "Aha! That's 5, 10, 15..."
Create your own math problem with blueberries as a picture. For example: 9 berries + 3 berries = 12 berries. When you set tasks for yourself, you understand better what addition and subtraction really mean.
Because your brain calculates easier when it sees order. Over time, your mind will get faster. You won't even need to consciously count every step. Your brain automates the counting. It remembers, for example: This is what a group of 5 looks like.
You'll become more confident. Faster. And soon you can focus on more challenging tasks. Try it with other fruits or vegetables too.
