[L3] Exploring Salmon Migration Numbers!
Practice
Lesson 3 is to practice estimating sums and differences by exploring how many Salmon return to their home rivers each year. CC Standard: 4.OA.A.3: Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. 4.NB.A.3: Use place value understanding to round multi-digit whole numbers to any place.

Salmon Math Journey Salmon fish are amazing travelers! They are born in freshwater lakes and rivers, and swim all the way to the ocean (sometimes thousands of miles!), and then return to the very same river where they were born to lay their eggs. Scientists think they "sniff out" their home river using their super sense of smell! Let’s explore how many Salmon swim in different rivers — and learn estimation while we do it!
