1. **State the problem:** We want to find the product of 2 and 38, i.e., calculate $2 \times 38$ using concrete objects. 2. **Use concrete objects:** The teacher trainee would gather 38 objects (like counters, blocks, or beads). 3. **Create two groups:** Make 2 groups, each containing 38 objects. 4. **Count total objects:** Count all objects in both groups together to find the total. 5. **Calculate mathematically:** Alternatively, multiply 2 by 38 using multiplication facts: $$2 \times 38 = 76$$ 6. **Explain:** The total number of objects in the two groups combined is 76, so $2 \times 38 = 76$. This hands-on approach helps understand multiplication as repeated addition or grouping.
