\item Use units, strips, and mats to evaluate $15 \times 5$.
\item Use place value cards to evaluate $15 \times 5$.
\item Use expanded notation to evaluate $175 \times 234$.  Be sure to
justify each step.
\item Use the instructional algorithm to evaluate $175 \times 234$.
\item Use units, mats, and strips to evaluate $637 \div 4$.
\item Use place value cards to evaluate $637 \div 4$.
\item Use the long division algorithm to evaluate $53,964 \div 210$.
	Check your work.
\item Use the scaffold algorithm to evaluate $53,964 \div 210$.
\item Use the short division algorithm to evaluate $53,964 \div 210$.
\item Evaluate $288_{nine} \times 7_{nine}$.
\item Evaluate $88_{nine} \times 32_{nine}$.
\item Evaluate $88_{nine} \div 12_{nine}$.
\item Evaluate $432_{five} + 224_{five}$.
\item Evaluate $643_{seven} - 244_{seven}$.
\item Use units, strips, and mats to evaluate $437+695$.  
\item Use place value cards to evaluate $437+695$.  
\item Use instructional algorithm to evaluate $437+695$.  
\item Use a place value diagram to evaluate $437+695$.  
\item Use units, strips, and mats to evaluate $953-679$.  
\item Use place value cards to evaluate $953-679$.  
\item Use instructional algorithm to evaluate $953-679$.  
\item Use a place value diagram to evaluate $953-679$.  
\item Draw an area diagram to represent $123 \times 65$.  You do not need
to put all of the grid lines in the area diagram.  Explain how this diagram
relates to the instructional algorithm for multiplcation.
