Candling Day 15

Today we candled eggs #3 and #4. It was amazing to observe the difference that only 7 days made in our eggs! 

Some of the things we noticed are - 

The eggs seem darker. 

We can't see as many veins. 

We can see something larger moving around inside the egg. (Especially egg #3!)

We are going to investigate these observations next week and report our findings on our Kidblog. 

Check out these amazing videos of our duck eggs on day 15!

Adding 3 Digit Numbers with Regrouping

This week in math we have been adding 3 digit numbers with and without regrouping. Everyone has done an excellent job showing their work and explaining why we regroup! It's important for students to know that we regroup because we are swapping out 10 smaller units that equal the same as 1 bigger unit. 10 ones can be exchanged for 1 ten. 10 tens can be exchanged for 1 hundred and so on. 

At the beginning of the week we worked with showing models of base ten blocks to visualize how we regroup. 

We love doing number talks and teaching one another! We worked on using the stacking strategy and mental math to solve addition story problems today.
