You can use the following website as a resource if your son/daughter needs assistance with Study Links 2.9 tonight:

https://www.everydaymathonline.com/free_resources_main.html?frnologin=1#

Then click on: 
- Algorithms in Everyday Mathematics
- Grade 4
- Subtraction

The two algorithms that we are focusing on are:
1.  Trade-First Subtraction Method
2.  Partial Differences Subtraction Method
