Curated OER
Multiplying in Any Order
In this mathematics worksheet, 2nd graders use counters to show an array. Then they write the multiplication fact for that array. Students also identify if the reverse of a multiplication fact is equal and explain why.
Curated OER
Multiplying by Two-Digit Numbers
In this mathematics worksheet, 6th graders find the product of a given equation. Then they use an array and find the sum of the partial products. Students also use zeros as place holders when necessary.
Curated OER
Multiplying Decimals
In this mathematics worksheet, 6th graders estimate the product and use an array to help them find the product. Then they find the exact product and locate where to put the decimal point in each.
