Build a Birdhouse

Before I build something, I make a plan. Then I gather the materials and tools I need. Here’s a step-by-step look at how I built a birdhouse.

I love to build! When I was little, I built towers with blocks. But the towers always fell down. Then I learned how to use tools. I built a

box for my mom. It stayed together! Now I’m a carpenter. I build things

with wood. I use tools like saws, hammers, drills, and screwdrivers.

I draw a plan for the birdhouse. I estimate how much wood I will need. I choose a board that’s the right length.

I measure 3 pieces for the sides and floor, 2 for the front and back, and 2 for the roof. (How many pieces are there in all?)

Can you guess what the most important tool in my toolbox is? It’s a ruler! Carpenters always say, “Measure twice, cut once.” That’s so we cut exactly the right size piece of wood we need for the job. It takes practice and skill to be a good carpenter. It also takes math. Read on to find out how I use math to build a birdhouse.

I cut the pieces from the board. I drill a hole so birds can go in and out. Then I carefully fit the pieces together.

Finally, I find a good spot outside for the birdhouse and put it up. The

estimate: to figure out about how much or how many of something

length: the longest side of something

measure: to find the size of something

carpenter: someone who builds with wood
