Solve the grouping problems for dogs, burgers, cats, and green blocks. Show addition, multiplication, and division sums.

Here are the solutions for the grouping problems:

Tell a story about the groups:
There are 6 groups of dogs, with 4 dogs in each group. How many dogs are there in total?

Here are the completed grouping problems:

Column 1: Dogs

• Groups of: $\boxed{6}$ groups of $\boxed{4}$
• Addition sum: $4+4+4+4+4+4 = \boxed{24}$
• Multiplication sum: $6 \times 4 = \boxed{24}$
• Division sum: $24 \div 6 = \boxed{4}$

Column 2: Burgers

• Groups of: $\boxed{5}$ groups of $\boxed{3}$
• Addition sum: $3+3+3+3+3 = \boxed{15}$
• Multiplication sum: $5 \times 3 = \boxed{15}$
• Division sum: $15 \div 5 = \boxed{3}$

Column 3: Cats

• Groups of: $\boxed{4}$ groups of $\boxed{6}$
• Addition sum: $6+6+6+6 = \boxed{24}$
• Multiplication sum: $4 \times 6 = \boxed{24}$
• Division sum: $24 \div 4 = \boxed{6}$

Column 4: Green blocks (tens)

• Groups of: $\boxed{6}$ groups of $\boxed{10}$
• Addition sum: $10+10+10+10+10+10 = \boxed{60}$
• Multiplication sum: $6 \times 10 = \boxed{60}$
• Division sum: $60 \div 6 = \boxed{10}$

Column 5: Green blocks (ones)

• Groups of: $\boxed{6}$ groups of $\boxed{4}$
• Addition sum: $4+4+4+4+4+4 = \boxed{24}$
• Multiplication sum: $6 \times 4 = \boxed{24}$
• Division sum: $24 \div 6 = \boxed{4}$

Column 6: Green blocks (tens)

• Groups of: $\boxed{5}$ groups of $\boxed{10}$
• Addition sum: $10+10+10+10+10 = \boxed{50}$
• Multiplication sum: $5 \times 10 = \boxed{50}$
• Division sum: $50 \div 5 = \boxed{10}$

Column 7: Red blocks (hundreds)

• Groups of: $\boxed{3}$ groups of $\boxed{100}$
• Addition sum: $100+100+100 = \boxed{300}$
• Multiplication sum: $3 \times 100 = \boxed{300}$
• Division sum: $300 \div 3 = \boxed{100}$
