Write the number names: a) 236 = b) 109 = Write the numerals: a) Four hundred seventy four = b) Nine hundred ninety seven =

Here are the solutions to the problems:

1. Write the number names:

• a) 236: Two hundred thirty-six
• b) 109: One hundred nine

2. Write the numerals:

• a) Four hundred seventy four: $\boxed{474}$
• b) Nine hundred ninety seven: $\boxed{997}$

3. Write in expanded form:

• a) $408 = \boxed{4}$ hundreds $\boxed{0}$ tens $\boxed{8}$ ones
• b) $890 = \boxed{800} + \boxed{90} + \boxed{0}$

4. Put >, < or = in the box:

• a) $300 + 60 + 8 = 368$ and $300 + 80 + 6 = 386$. $368 \boxed{<} 386$
• b) $4 \text{ hundreds } 3 \text{ tens } = 400 + 30 = 430$. $430 \boxed{=} 430$
• c) $1 \text{ more than } 393 = 394$. $1 \text{ less than } 390 = 389$. $394 \boxed{>} 389$

5. Write the numbers from 790 to 810:

• $790, 791, 792, 793, 794, 795, 796, 797, 798, 799, 800, 801, 802, 803, 804, 805, 806, 807, 808, 809, 810$

6. Order numbers:

• a) Write in ascending order (smallest to largest): 342, 792, 432, 423 $\boxed{342, 423, 432, 792}$
• b) Write in descending order (largest to smallest): 236, 306, 263, 632 $\boxed{632, 306, 263, 236}$

7. Discover the pattern and complete it:

• a) 657, 667, 677, ... (The pattern is adding 10 each time) $657, 667, 677, \boxed{687}, \boxed{697}, \boxed{707}$
• b) 420, 415, 410, ... (The pattern is subtracting 5 each time) $420, 415, 410, \boxed{405}, \boxed{400}, \boxed{395}$
