Student activist Jonathan Butler and Congressman John Lewis sit down to discuss the Eyes on the Prize series and the Civil Rights Movement in this video from Eyes on the Prize: Then and Now. Lewis reflects on the 1965 Selma to Montgomery protest march. Shortly after the march began, Alabama State troopers met the marchers with violence as they crossed Selma's Edmund Pettus Bridge. Lewis also describes experiences from his childhood and youth, when he began to question segregation and other inequalities, and first's student activists. [4:28]

In this interactive, use logic to solve three riddles involving a jumping frog competition. Then, using knowledge of inequalities and rational numbers, place the frogs in the correct range from 0 to 5 on a number line. The fractions, mixed numbers, and decimals (in feet and inches) are randomized so that the range on the number line is different each time the riddles appear. The accompanying classroom activity includes a concept review and a response sheet handout to support the online work.

In this interactive, use logic to solve three riddles involving high-jump performers in a flea circus. Then, using knowledge of inequalities, place the fleas in the appropriate range on a vertical number line. Numbers are randomized so that the range on the vertical number line is different each time one of the three riddles appears. The accompanying classroom activity includes a fraction/decimal concept review and response sheets to support the online work.

In this interactive, use logic to solve three riddles involving a jumping wallaby competition. Then, using knowledge of inequalities and rational numbers, place the wallabies on the correct range from -5 to 5 on the number line. Numbers are randomized so that the range on the number line is different each time the riddles appear. The accompanying classroom activity includes a concept review and response sheets to support the online work.
